Complex Queries in solr
Hi,
Is it possible to search complex queries like
(consult* or advis*) NEAR(40) (fee or retainer or salary or bonus)
in solr

i just tested it whether our 'beautifu' parser supports it, and funnily
enough, it does :-)
https://github.com/romanchyla/montysolr/commit/f88577345c6d3a2dbefc0161f6bb07a549bc6b15
but i've (kinda) given up hope that people need powerful query parsers in
the lucene world, the LUCENE-5014 is there sitting without attention for
eons ... so your best bet is probably to use LucidWorks parser (but i don't
know if it supports proximity searches combined with wildcards and
booleans) or you can create a custom query plugin that builds the following
query
spanNear([spanOr([SpanMultiTermQueryWrapper(all:consult*),
SpanMultiTermQueryWrapper(all:advis*)]), spanOr([all:fee,
all:retainer, all:salary, all:bonus])], 4, true)
you can draw inspiration from here:
https://github.com/romanchyla/montysolr/blob/master/contrib/antlrqueryparser/src/java/org/apache/lucene/queryparser/flexible/aqp/builders/AqpNearQueryNodeBuilder.java
https://github.com/romanchyla/montysolr/blob/master/contrib/antlrqueryparser/src/java/org/apache/lucene/queryparser/flexible/aqp/builders/SpanConverter.java
but i think you are aware that such a query is NOT going to be very
efficient. especially when proximity=40 ;-)

You should star reading from here:
https://cwiki.apache.org/confluence/display/solr/The+Standard+Query+Parser and
you should have a look at Fuzzy Searches section. On the other hand read
here: http://wiki.apache.org/solr/FunctionQuery
