I've started trying edismax, and have noticed that my relevancy ranking is messed up with edismax because, according to the debug output, it's using bigrams instead of phrases and inexplicably ignoring a couple of the pf fields. While the hit count isn't changing, this kills my ability to boost exact title matches (or, I would guess, exact-anything-else matches, too).
debugQuery output can be seen at: http://paste.lisp.org/display/91582 That's the exact same query except for the defType. Note that instead of looking in the 'pf' fields for the search string "gone with the wind", it's looking individually for "gone with", "with the", and "the wind". edismax is also completely ignoring the title_a and title_ab fields, which are defined as "exactmatcher" as follows. <!-- Full string, stripped of \W and lowercased, for exact and left-anchored matching --> <fieldType name="exactmatcher" class="solr.TextField" omitNorms="true"> <analyzer> <tokenizer class="solr.KeywordTokenizerFactory"/> <filter class="schema.UnicodeNormalizationFilterFactory" version="icu4j" composed="false" remove_diacritics="true" remove_modifiers="true" fold="true"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.TrimFilterFactory"/> <filter class="solr.PatternReplaceFilterFactory" pattern="[^\p{L}\p{N}]" replacement="" replace="all" /> </analyzer> </fieldType> Any help on this would be much appreciated. -- Bill Dueber Library Systems Programmer University of Michigan Library
