solr4

问题 While attempting to upgrade from Solr 4.3.0 to Solr 4.4.0 I ran into this exception: java.lang.IllegalArgumentException: enablePositionIncrements=false is not supported anymore as of Lucene 4.4 as it can create broken token streams which led me to this issue. I need to be able to match queries irrespective of intervening stopwords (which used to work with enablePositionIncrements="true"). For instance: "foo of the bar" would find documents matching "foo bar", "foo of bar", and "foo of the bar

问题 Boosting by date field in solr is defined as: {!boost b=recip(ms(NOW,datefield),3.16e-11,1,1)} I looked everywhere (examples: Solr Dismax Config for Boost Scoring and Solr boost for multivalued date field and they all reference the SolrRelevancyFAQ), same definition that is used. But I found that this is not boosting my results sufficiently. How can I make this date boosting stronger? User is searching for two keywords. Both items contain both keywords (in same order) in both title and

Is there any way we can destroy the mark if it is no longer used. 回答1: CursorMark does not require server state. It's just a value referring to some internal information. So, there should be no memory impact from using it with multiple

问题 I have some items in my index (Solr. 4.4), which contain names like Foobar 135g , where the 135g refers to some weights. Searching for foobar or foobar 135 does work, but when I try to search for the exact phrase foobar 135g , nothing is found. I analysed the query inside the solr admin panel "Analysis".
