Hi, You don't need to duplicate the content into two fields to achieve this. Try this:
q=mount OR mount* The exact match will always get higher score than the wildcard match because wildcard matches uses "constant score". Making this work for multi term queries is a bit trickier, but something along these lines: q=(mount OR mount*) AND (everest OR everest*) -- Jan Høydahl, search solution architect Cominvent AS - www.cominvent.com Training in Europe - www.solrtraining.com On 10. aug. 2010, at 09.38, Geert-Jan Brits wrote: > you could satisfy this by making 2 fields: > 1. exactmatch > 2. wildcardmatch > > use copyfield in your schema to copy 1 --> 2 . > > q=exactmatch:mount+wildcardmatch:mount*&q.op=OR > this would score exact matches above (solely) wildcard matches > > Geert-Jan > > 2010/8/10 yandong yao <yydz...@gmail.com> > >> Hi Bastian, >> >> Sorry for not make it clear, I also want exact match have higher score than >> wildcard match, that is means: if searching 'mount', documents with 'mount' >> will have higher score than documents with 'mountain', while 'mount*' seems >> treat 'mount' and 'mountain' as same. >> >> besides, also want the query to be processed with analyzer, while from >> >> http://wiki.apache.org/lucene-java/LuceneFAQ#Are_Wildcard.2C_Prefix.2C_and_Fuzzy_queries_case_sensitive.3F >> , >> Wildcard, Prefix, and Fuzzy queries are not passed through the Analyzer. >> The >> rationale is that if search 'mounted', I also want documents with 'mount' >> match. >> >> So seems built-in wildcard search could not satisfy my requirements if i >> understand correctly. >> >> Thanks very much! >> >> >> 2010/8/9 Bastian Spitzer <bspit...@magix.net> >> >>> Wildcard-Search is already built in, just use: >>> >>> ?q=umoun* >>> ?q=mounta* >>> >>> -----Ursprüngliche Nachricht----- >>> Von: yandong yao [mailto:yydz...@gmail.com] >>> Gesendet: Montag, 9.
