: My application needs the QueryParser (by way of QueryParsing) to be
: set to AND mode, not the default of OR. There isn't currently a
: setting to control this.
I think by now everyone knows my prediliction for writing custom
RequestHandlers -- but i agree that something like this would be a good
idea as a way to modify the properties of the "default" SolrQueryParser.
my one suggestion would be that we should support schema.xml declarations
for all of the "setable" properties of the Lucene QueryParser...
<solrQueryParser defaultOperator="AND"
fuzzyMinSim="0.5"
fuzzyPrefixLength="2"
locale="???"
lowerCaseExpandTerms="true"
phraseSlop="5" />
...i'm not saying I expect Erik to put in all the code to deal with all of
those now (unless you really want to Erik), just that it would be a good
idea if the config syntax for the default OP left room for them as
children of a larger solrQueryParser config block.
:
: I've added it locally using the patch below. Any objections to me
: committing this?
:
: I actually feel strongly that the default setting should be AND
: instead of OR, but I left it at OR in this patch for backwards
: compatibility :) (but would gladly change it to AND if there is
: consensus).

: Thanks,
: Erik
