Default query parser operator
Hi all,
Is it possible to change the query parser operator for a specific field
without having to explicitly type it in the search field?
For example, I'd like to use:
http://localhost:8983/solr/search/?q=field1:word token field2:parser syntax
instead of
http://localhost:8983/solr/search/?q=field1:word AND token field2:parser
syntax
But, I only want it to be applied to field1, not field2 and I want the
operator to always be AND unless the user explicitly types in OR.
Thanks,
Brian Lamb

You might be able to do something like this in a custom QParser. look at
the LuceneQParser as an example, but replace usages of QueryParser with
your own subclass of QueryParser where you override the getBooleanQuery
method and muck with the Occur property of the BooleanClauses if they all
have the same field.
the thing you might not want though is that by the time you get to that
part of the API there's no way to tell the diff between...
field1:foo field1:bar
field1:(foo bar)
...not sure if you care.
you'd also have to consider what you want to happen if some one entered...
field1:foo field1:bar field1:baz field2:xxxxxx
...because at that layer of the API it's a sigle list of BooleanClauses.
Another thing to consider is that the new QueryParser framework might make
dealing with this a lot easier (but i'm jues guessing, i'm not really
familiar with it)...

It could, it would be a little bit clunky but that's the direction I'm
heading.

Hi Brian could your front end app do this field query logic?
(assuming you have an app in front of solr)

There's no feature in Solr to do what you ask, no. I don't think.

Hi Jonathan,
Thank you for your reply. Your point about my example is a good one. So let
me try to restate using your example. Suppose I want to apply AND to any
search terms within field1.
Then
field1:foo field2:bar field1:baz field2:bom
would by written as
http://localhost:8983/solr/?q=field1:foo OR field2:bar OR field1:baz OR
field2:bom
But if they were written together like:
http://localhost:8983/solr/?q=field1:(foo baz) field2:(bar bom)
I would want it to be
http://localhost:8983/solr/?q=field1:(foo AND baz) OR field2:(bar OR bom)
But it sounds like you are saying that would not be possible.
Thanks,
Brian Lamb

Nope, not possible.
I'm not even sure what it would mean semantically. If you had default
operator "OR" ordinarily, but default operator "AND" just for "field2",
then what would happen if you entered:
field1:foo field2:bar field1:baz field2:bom
Where the heck would the ANDs and ORs go? The operators are BETWEEN the
clauses that specify fields, they don't belong to a field. In general,
the operators are part of the query as a whole, not any specific field.
In fact, I'd be careful of your example query:
q=field1:foo bar field2:baz
I don't think that means what you think it means, I don't think the
"field1" applies to the "bar" in that case. Although I could be wrong,
but you definitely want to check it. You need "field1:foo field1:bar",
or set the default field for the query to "field1", or use parens
(although that will change the execution strategy and ranking):
q=field1:(foo bar) ....
At any rate, even if there's a way to specify this so it makes sense,
no, Solr/lucene doesn't support any such thing.

I feel like this should be fairly easy to do but I just don't see anywhere
in the documentation on how to do this. Perhaps I am using the wrong search
parameters.
