1. Do not use stopwords. Ever. Especially with names. 2. Do not use stemming with names. “Bill Gates” is not the same as “Bill Gate”. You aren’t, but I thought I’d include that. 3. Mixing partail word matches and full word matches in the same search is likely to give odd results. 4. Your requirements don’t say anything about phrase matches, which are very important. 5. What synonmys are you using, are they tuned for names, like “william, bill”? If not, remove that. 6. Why are you using WordDelimiterGraphFilterFactory? Do you want to split “DeForest” into “De Forest”? 7. What are you using payloads for?
You can use weights in the edismax parser to give different fields different importance in matching. I would also put weights on phrase matches. I usually double the weights for phrases because the native weighting for phrases in Solr isn’t enough. Something like this: <str name=“qf”>name^4 name_ngram^2 infotext</str> <str name=“pf”>name^8 name_ngram^4 infotext^2</str> Get rid of: * StopFilterFactory * SynonymFilterFactory * WordDelimiterFilterFactory With the remaining filters, you’ll never have duplicates, so you can also get rid of RemoveDupliicatsTokenFilterFactory if you want. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Mar 31, 2020, at 6:00 AM, nileshwagh24 <waghniles...@gmail.com> wrote: > > In need to score partial match in NAME field higher than exact match in > INFOTEXT field.Actually I need to sort my SOLR result based on following > five conditions > > 1.First, results with a whole word match on the first or second word in the > NAME go on top. > > 2.Then, results with a whole word match elsewhere in the NAME. > > 3.Then, results with a partial word match anywhere in the NAME. > > 4.Then, results with a whole word match in the INFOTEXT. > > 5.Finally, results with a partial word match in the INFOTEXT. > > I have added descriptionExact field for INFOTEXT and titleExact field for > NAME. > > For this I have added four fields like > titleExact,titlePartial,descriptionExact,DescriptionPartial and boosted > titleExact score higher than all others. > > But I am not getting result as expected. > > Following are the field definitions for exact and partial field > > > <fieldType name="text_general" class="solr.TextField" > positionIncrementGap="100" multiValued="true"> > <analyzer type="index"> > <charFilter class="solr.MappingCharFilterFactory" > mapping="mapping-ISOLatin1Accent.txt"/> > <tokenizer class="solr.KeywordTokenizerFactory"/> > <filter class="solr.StopFilterFactory" words="stopwords.txt" > ignoreCase="true"/> > <filter class="solr.LowerCaseFilterFactory"/> > <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> > </analyzer> > <analyzer type="query"> > <charFilter class="solr.MappingCharFilterFactory" > mapping="mapping-ISOLatin1Accent.txt"/> > <tokenizer class="solr.KeywordTokenizerFactory"/> > <filter class="solr.SynonymFilterFactory" expand="true" > ignoreCase="true" synonyms="synonyms.txt"/> > <filter class="solr.StopFilterFactory" words="stopwords.txt" > ignoreCase="true"/> > <filter class="solr.LowerCaseFilterFactory"/> > <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> > </analyzer> > </fieldType> > <fieldType name="text_general_partial" class="solr.TextField" > positionIncrementGap="100" multiValued="true"> > <analyzer type="index"> > <charFilter class="solr.MappingCharFilterFactory" > mapping="mapping-ISOLatin1Accent.txt"/> > <tokenizer class="solr.WhitespaceTokenizerFactory"/> > <filter class="solr.DelimitedPayloadTokenFilterFactory" delimiter="$" > encoder="float"/> > <filter class="solr.SynonymFilterFactory" expand="true" ignoreCase="true" > synonyms="synonyms.txt"/> > <filter class="solr.StopFilterFactory" words="stopwords.txt" > ignoreCase="true"/> > <filter class="solr.WordDelimiterGraphFilterFactory" > catenateNumbers="1" generateNumberParts="1" protected="protwords.txt" > splitOnCaseChange="1" generateWordParts="0" preserveOriginal="1" > catenateAll="0" catenateWords="1"/> > <filter class="solr.EdgeNGramFilterFactory" maxGramSize="15" > minGramSize="3"/> > <filter class="solr.LowerCaseFilterFactory"/> > <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> > </analyzer> > <analyzer type="query"> > <charFilter class="solr.MappingCharFilterFactory" > mapping="mapping-ISOLatin1Accent.txt"/> > <tokenizer class="solr.WhitespaceTokenizerFactory"/> > <filter class="solr.DelimitedPayloadTokenFilterFactory" delimiter="$" > encoder="float"/> > <filter class="solr.SynonymFilterFactory" expand="true" > ignoreCase="true" synonyms="synonyms.txt"/> > <filter class="solr.StopFilterFactory" words="stopwords.txt" > ignoreCase="true"/> > <filter class="solr.WordDelimiterGraphFilterFactory" > catenateNumbers="1" generateNumberParts="1" protected="protwords.txt" > splitOnCaseChange="1" generateWordParts="0" preserveOriginal="1" > catenateAll="0" catenateWords="1"/> > <filter class="solr.LowerCaseFilterFactory"/> > <filter class="solr.RemoveDuplicatesTokenFilterFactory"/> > </analyzer> > </fieldType> > > Any help will be appreciated > > > > -- > Sent from: https://lucene.472066.n3.nabble.com/Solr-User-f472068.html
