Hi, One trick is to index a special token at the beginning of the content and do a phrase query for your terms and the special token with little or no slop. You can also use Lucene's SpanFirstQuery but it's not yet exposed in Solr. There's a patch for trunk exposing the SpanFirstQuery in Solr's Edismax query parser.
It cannot do progressively smaller boosts to words further from the start by itself. https://issues.apache.org/jira/browse/SOLR-3925 Cheers, Markus -----Original message----- > From:YooKyuseok <kyuseok....@samsung.com> > Sent: Fri 26-Oct-2012 14:39 > To: solr-user@lucene.apache.org > Subject: how solr to boost term value at the start of ther field? > > i am kyuseok in Republic of Korea. > nice to meet you. > > i am searching about 'solr boost term postion' and struggling with this > isusse. > and i still didn`t solve it. > > i am serving video contents search server. > and my client require the contents which match the value at the start of > field shoud be displayed first. > > so i want to rank like below > > *search word : indiana > *result docs. > 1. indiana Jones > 2.
