Re: Search for All CAPS words
So, what you want is to duplicate a specific token, rename one of the copies, and inject it with the same offset as the original. So GATE => gate, _gate but gate=>gate. That, to me, is a custom token filter. You can probably use KeywordRepeatFilterFactory as a base: http://www.solr-start.com/javadoc/solr-lucene/org/apache/lucene/analysis/miscellaneous/KeywordRepeatFilterFactory.html (you can click through to the Filter and then source from there).

Re: Search for All CAPS words
Thanks and I did think of the copy field option. So what you are suggesting is that I have a copyfield in which I do not keep the lowercase factory analyzer in my indexing/query chains. I am afraid that would not help if my search query is complex with many words (say a boolean with proximity operators) because the full search string would have go into the copyfield (not having the lowercase). The rest of the words other than /GATE/ wouldnt match properly then.

Re: Search for All CAPS words
Have you tried copyField with different field type for different fields yet? That would be my first step. Make the copied field indexed-only, not stored for efficiency. And you can then either search against that copied field directly or use eDisMax against both fields and give that field a higher priority. Regards, Alex.

Search for All CAPS words
Hi, I need the capability to search for /GATE/ separately from /gate/. I cannot remove the lowercase filter factory in both my search and analysis chains since that will break many other search scenarios. Is there a way to payload/mark an ALL CAPS word in the index analyzer chain before it gets lowercased (by the lowercasefilterfactory) so that I can search it with some custom grammar and logic in my query parser. Say I want: Field:_gate to match /GATE/ only Field:gate to match both /GATE/ and /gate/ Any pointers would be helpful. thanks Ritesh -- View this message in context: http://lucene.472066.n3.nabble.com/Search-for-All-CAPS-words-tp4219893.html Sent from the Solr - User mailing list archive at Nabble.com.
