How can I set the defaultOperator to be AND?
Hi guys,
How can I set the defaultOperator to be AND?
If I add the following line to the schema.xml, even if I do a search
'title:"test" OR author:"me"', it will returns documents matching
'title:"test" AND author:"me"':
<solrQueryParser defaultOperator="AND"/>
solr version: 6.0
I know that I can overwrite the query with q.op, but this is not that
convenient...
I would need to write a complex query for a simple search '(a:x AND b:y)
OR c:z'
Kind regards,
Bastien Latard

With Solr 6.0 I've had to set mm=100% & q.op=AND for a full AND query (and
mm=1 & q.op=OR for a full OR query).

Thank you Erick.
You're fully right that it can be an expected behavior to get more docs
with more words...why not...
However, when I set the default OP to "AND" in solrconfig.xml, then a
simple query "q=a OR b" doesn't work as expected... as described in the
previous email:
-> a search 'title:"test" OR author:"me"' will returns documents
matching 'title:"test" AND author:"me"'
Kind regards,
Bastien

Posted by Erick Erickson <er...@gmail.com>.
Defaulting to "OR" has been the behavior since forever, so changing the
behavior now is just not going to happen. Making it fit a new version of
"correct" will change the behavior for every application out there that has
not specified the default behavior.
There's no a-priori reason to expect "more words to equal fewer docs", I
can just as easily argue that "more words should return more docs". Which
you expect depends on your mental model.
And providing the default op in your solrconfig.xml request handlers allows
you to implement whatever model your application chooses...
Best,
Erick

Thank you Shawn, Jan and Georg for your answers.
Yes, it seems that if I simply remove the defaultOperator it works well
for "composed queries" like '(a:x AND b:y) OR c:z'.
But I think that the default Operator should/could be the AND.
Because when I add an extra search word, I expect that the results get
more accurate...

The settings in the schema for default field and default operator were
deprecated a long time ago. I actually have no idea whether they are
even supported in newer Solr versions.
The q.op parameter controls the default operator, and the df parameter
controls the default field. These can be set in the request handler
definition in solrconfig.xml -- usually in "defaults" but there might be
reason to put them in "invariants" instead.
If you're using edismax, you'd be better off using the mm parameter
rather than the q.op parameter. The behavior you have described above
sounds like a change in behavior (some call it a bug) introduced in the
5.5 version:
https://issues.apache.org/jira/browse/SOLR-8812
If you are using edismax, I suspect that if you set mm=100% instead of
q.op=AND (or the schema default operator) that the problem might go away
... but I am not sure. Someone who is more familiar with SOLR-8812
probably should comment.

Any news?
Remember:
If I add the following line to the schema.xml, even if I do a search
'title:"test" OR author:"me"', it will returns documents matching
'title:"test" AND author:"me"':
<solrQueryParser defaultOperator="AND"/>

Yes Jan, I'm using edismax.
This is (a part of) my requestHandler:
<requestHandler name="/select" class="solr.SearchHandler">
<lst name="defaults">
<str name="indent">false</str>
<str name="echoParams">explicit</str>
<int name="rows">10</int>

[...]
Is there anything I should do to improve/fix it?

Hi
Which query parser are you using? If using edismax yo may be hitting a recent bug concerning default operator and explicit boolean operators.
