My colleague, after some digging, found in SolrQueryParser
(around line 62) setLowercaseExpandedTerms(false); The default for Lucene is true. Was this intentional? Or an oversight? Perhaps it's not related to my problem, but it seems that it might be. Thanks in advance! On 4/26/07, Michael Kimsal <[EMAIL PROTECTED]> wrote:
type:changelog AND ( ( (listing:Fox) or (listing:Fox*) or (listing:*Fox) ) ) and type:changelog AND ( ( (listing:fox) or (listing:fox*) or (listing:*fox) ) ) Is this to do with the wildcards? Actually, I've just answered my own question. type:changelog AND ( ( (listing:fox) ) ) and type:changelog AND ( ( (listing:Fox) ) ) give the same results. But adding in the or listing:fox* or listing:*fox is always case-sensitive. However, http://wiki.apache.org/lucene-java/LuceneFAQ#head-133cf44dd3dff3680c96c1316a663e881eeac35aseems to say that wildcard searches are not case-sensitive. Unless someone can point out a way around this, it seems I'll need to manually reindex and lower-case everything on the way in, then reformat my search queries to be lower-case as well.
