Expanding sets of words
Is there a way to query for combinations of two sets of words? For
example, if I had
(java or groovy or scala)
(programming or coding or development)
Is there a query parser that, at query time, would expand that into
combinations like
java programming
groovy programming
scala programming
java coding
java development
....
etc etc etc
Thanks!
Mike

Re: Expanding sets of words

Ah... and the answer is:
curl
"http://localhost:8983/solr/select/?q=(assembly+W+language+OR+scala)+W+programming\
&df=features&defType=surround&indent=true"
IOW, any quoted phrase like "a b c d" can be written in surround as a W b W
c W d.
Presto!
I'll make sure that example is in the book as well.

Does this work with mutli-word terms?
(common lisp or assembly language)
(programming or coding or development)
I tried:
{!surround}(common lisp OR assembly language) W (programming)
but that returns a parse error.
Putting quotes around the multi-word terms parses but returns 0 results
{!surround}("common lisp" OR "assembly language") W (programming)

Re: Expanding sets of words

Yes, with the Solr "surround" query parser:
q=(java OR groovy OR scala) W (programming OR coding OR development)
BUT... there is the caveat that the surround query parser does no analysis.
So, maybe you need "Java OR java" etc. Or, if you know that the index is
lower case.
Try this dataset:
curl http://localhost:8983/solr/collection1/update?commit=true -H
'Content-type:application/csv' -d '
id,features
doc-1,java coding
doc-2,java programming
doc-3,java development
doc-4,groovy coding
doc-5,groovy programming
doc-6,groovy development
doc-7,scala coding
doc-8,scala programming
doc-9,scala development
doc-10,c coding
doc-11,c programming
doc-12,c development
doc-13,java language
doc-14,groovy language
doc-15,scala language'
And try these commands:
curl "http://localhost:8983/solr/select/?q=(java+OR+scala)+W+programming\
&df=features&defType=surround&indent=true"
curl "http://localhost:8983/solr/select/?\
q=(java+OR+scala)+W+(programming+OR+coding)\
&df=features&defType=surround&indent=true"
curl "http://localhost:8983/solr/select/\
?q=(java+OR+groovy+OR+scala)+W+(programming+OR+coding+OR+development)\
&df=features&defType=surround&indent=true"
The LucidWorks Search query parser also supports NEAR, BEFORE, and AFTER
operators, in conjunction with OR and "-" to generate span queries:
q=(java OR groovy OR scala) BEFORE:0 (programming OR coding OR development)

Subject: Expanding sets of words
Is there a way to query for combinations of two sets of words? For
example, if I had
(java or groovy or scala)
(programming or coding or development)
Is there a query parser that, at query time, would expand that into
combinations like
java programming
groovy programming
scala programming
java coding
java development
....
etc etc etc
Thanks!
Mike

How many such combinations are there? If these are limited
in number, and can be pre-defined, the easiest way might be
to use synonyms:
http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.SynonymFilterFactory
If that does not meet your needs, you will probably need to
write a custom query parser, which is not too difficult:
