[jira] [Created] (SOLR-3823) Parentheses in a boost query cause
errors
Mathos Marcer created SOLR-3823:
-----------------------------------
Summary: Parentheses in a boost query cause errors
Key: SOLR-3823
URL: https://issues.apache.org/jira/browse/SOLR-3823
Project: Solr
Issue Type: Bug
Components: query parsers
Affects Versions: 4.0-BETA
Environment: Mac, jdk 1.6, Chrome
Reporter: Mathos Marcer
When using a boost query (bq) that contains a parentheses (like this example from the Relevancy Cookbook section of the wiki):
? defType = dismax
& q = foo bar
& bq = (*:* -xxx)^999
You get the following error:
org.apache.lucene.queryparser.classic.ParseException: Cannot parse '-xxx)': Encountered " ")" ") "" at line 1, column 12. Was expecting one of: <EOF> <AND> ... <OR> ... <NOT> ... "+" ... "-" ... <BAREOPER> ... "(" ... "*" ... "^" ... <QUOTED> ... <TERM> ... <FUZZY_SLOP> ... <PREFIXTERM> ... <WILDTERM> ... <REGEXPTERM> ... "[" ... "{" ... <NUMBER> ...

Jack Krupansky commented on SOLR-3823:
--------------------------------------
bq. ...this is how subqueries have always worked with QParsers
Is there any wiki/Javadoc that documents this behavior?
I would also note that both the dismax and edismax wiki pages for "bq" say:
bq. A raw query string (in the SolrQuerySyntax)
which is not right. We know it uses defType, but we clearly need the precise language as it is supposed to be (noting the comments by hossman.)

bq. bq is parsed with the defType specified parser. Rather it should, like fq's, default to the "lucene" query parser.
Sounds reasonable for fq and bq to be parsed the same way, but it seems unrelated to this specific Jira.

Erick Erickson commented on SOLR-3823:
--------------------------------------
James:
The problem was quite the opposite. When there was NO space in the bq clause it'd fail like this, i.e.
bq=(stuff). And when there was space, I don't think it worked at all....
But yeah, it'd be good to have both parens and negative boosts...

bq. bq is parsed with the defType specified parser. Rather it should, like fq's, default to the "lucene" query parser.
Sounds reasonable for fq and bq to be parsed the same way, but it seems unrelated to this specific Jira.
And this also begs the question of why bq shouldn't simply be a global query parameter like fq. I don't see any reason why a multiplicative boost shouldn't apply to a non-dismax/edismax query - but again this is outside the scope of this specific Jira.

Thanks, Hoss, you're right...
But I can get this to fail both with BETA and today's trunk with the example data.

Interestingly this works: (note the space after "bq"),
{noformat}
http://localhost:8983/solr/select?q=foo&defType=edismax&bq =(name:nonsense -xxx)^999
{noformat}
This fails (spaces around parens, there was an issue with non-space parens lately, but apparently it's unrelated.)

Erick Erickson resolved SOLR-3823.
----------------------------------
Resolution: Invalid
The error is because of the colon character, it has meaning in a query and must be escaped. See: http://lucene.apache.org/core/3_6_1/queryparsersyntax.html.
So I'll close this as invalid, if you disagree please let us know.
BTW, it's better to raise this kind of question on the user's list rather than open a JIRA, at least until you're sure it's really a bug.

[jira] [Commented] (SOLR-3823) Parentheses in a boost query cause
errors
Posted by "James Dyer (JIRA)" <ji...@apache.org>.

James Dyer commented on SOLR-3823:
----------------------------------
Hoss,
I appreciate you fixing this, but I would rather get a fix that preserves the negative boost support (SOLR-3278). I guess I don't understand the bug this issue was addressing. Is it simply that "bq" would fail if extra whitespace was in the query? Could we write a failing testcase for that? Do you see a reason why it would be difficult to fix this and retain the negative boosts?
The discussion of LUCENE-4378 is pertinent: we have products in our index that we either do not sell or we know most of our customer do not want. Yet they often score very high. The only way I can reliably prevent these from becoming top hits is to use a negative boost. I would imagine this is a frequent requirement.
I'm more than willing to contribute for this, but I couldn't tell that this issue was an actual problem or a case of users putting whitespace where it doesn't belong and prior versions being more forgiving.

bq. I couldn't tell that this issue was an actual problem or a case of users putting whitespace where it doesn't belong and prior versions being more forgiving.
James: the core of the bug was your use of SolrPluginUtils.parseFieldBoosts to try and parse the bq params.
This is not safe -- if you look at the method it is an extremely trivial utility that is specific for parsing qf/pf style strings containing a list of field names and boosts. it's _not_ a safe way to parse an arbitrary query string, and any non trivial query string can cause problems with it.
AS you noted in SOLR-3278, parseFieldBoosts is used for parsing the "bf" param and that's actually a long standing unsafe bug as well (SOLR-2014) but since functions tend to be much simpler, it's historically been less problematic. when people run into problems with it, the workarround is to use "bq={!func}..." instead.
bq. I would rather get a fix that preserves the negative boost support
Since SOLR-3278 had not been released publicly outside of the ALPHA/BETA, my first priority was to fix the regression compared to 3.x where non-trivial bq queries worked fine.
The documented method of dealing with "negative boosting" in solr is actually the type of query that was the crux of this bug report, and i updated the tests you added in SOLR-3278 to use that pattern...
https://wiki.apache.org/solr/SolrRelevancyFAQ#How_do_I_give_a_negative_.28or_very_low.29_boost_to_documents_that_match_a_query.3F
I have no objections to supporting "true" negative boosts, but i think the right way to do it is in the query parsers / QParsers themselves (so that the boosts can be on any clause) and not just as a special hack for bq/bf (the fact that it works in bf is actualy just a fluke of it's buggy implementation) but as you can see in LUCENE-4378 this is a contentious idea.

[jira] [Updated] (SOLR-3823) Parentheses in a boost query cause

Hoss Man updated SOLR-3823:
---------------------------
Description:
When using a boost query (bq) that contains a parentheses (like this example from the Relevancy Cookbook section of the wiki):
{noformat}
? defType = dismax
& q = foo bar
& bq = (*:* -xxx)^999
{noformat}
You get the following error:

1) editing the issue description to include "noformat" tags -- i think Erick was getting confused by the "\*:\*" showing up as just ":"
2) i can't reproduce the described problem. When i tried using the solr example data, this request worked just fine...

-------------------------------------
I'm glad I'm not just going crazy :-)
I did notice while the space before the equal sign (ie "bq =(name:nonsense -xxx)^999") doesn't produce a parsing error, comparing results between 3.6 and 4.0 BETA, it doesn't appear to be applying the boost. In fact I get the same results as if I didn't have the "bq" option there at all.

Hoss Man commented on SOLR-3823:
--------------------------------
bq. Sorry to chime in after this issue has been marked as resolved, but .... it doesn't seem right to me that bq is parsed with the defType specified parser.
I don't understand this comment -- I see no evidence that "bq" is incorrectly using the defType parser in either dismax or edismax.
In both cases null is passed to the subQuery() call for bq allowing it inherit the defTYpe from the _localparams_ of the main "q" string (which is appropriate since the bq is an implicit subquery added to the main query) but not a global defType. ie, in the first example below, the "lucene" parser would be used to parse the bq, while in the second example the "yyy" parser would be used because of the explicit defType localparam...
{noformat}
/select?qf=name+text&defType=xxx&q={!edismax}mainquery&bq=myboost
/select?qf=name+text&defType=xxx&q={!edismax defType=yyy}mainquery&bq=myboost
{noformat}
...this is how subqueries have always worked with QParsers. if you think this should be reconsidered, please open a specific issue.
(NOTE: fq's are not subqueries of the main query, so they don't look at the "q" at all)

Jack Krupansky commented on SOLR-3823:
--------------------------------------
It turns out that it is the white space that causes the problem.
Looking at the code, I see that edismax calls SolrPluginUtils.parseFieldBoosts to "parse" the "bq" value, which is absurd since it simply breaks up the param value based on whitespace, even in the middle of the query. Then the code calls QParser.subQuery to parse the portions of the query, which of course makes no sense unless the original query contained no whitespace or was a sequence of non-white space queries separated with whitespace.
Dismax, OTOH, treats "bq" as an array of query strings (multiple "bq" params) and parses each as a separate sub-query.
Edismax in 3.6/3.6.1 has the old dismax code.
The culprit? SOLR-3278: "edismax support for negative boost with "bq" parameter" introduced the error, back in March.

> Key: SOLR-3823
> URL: https://issues.apache.org/jira/browse/SOLR-3823
> Project: Solr
> Issue Type: Bug
> Components: query parsers
> Affects Versions: 4.0-BETA
> Environment: Mac, jdk 1.6, Chrome
> Reporter: Mathos Marcer
>
> When using a boost query (bq) that contains a parentheses (like this example from the Relevancy Cookbook section of the wiki):
> {noformat}
> ? defType = dismax
> & q = foo bar
> & bq = (*:* -xxx)^999
> {noformat}
> You get the following error:
> org.apache.lucene.queryparser.classic.ParseException: Cannot parse '-xxx)': Encountered " ")" ") "" at line 1, column 12. Was expecting one of: <EOF> <AND> ... <OR> ... <NOT> ... "+" ...
