Hi All,
Last day I was able to configure Solr Suggester for recommendation in my
site with the following settings
<field name="query_suggest" type="text_suggester" indexed="true"
stored="true" />
<fieldType name="text_suggester" class="solr.TextField"
positionIncrementGap="100" multiValued="true">
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
<searchComponent name="suggest" class="solr.SuggestComponent">
<lst name="suggester">
<str name="name">mySuggester</str>
<str name="lookupImpl">AnalyzingLookupFactory</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="field">query_suggest</str>
<str name="suggestAnalyzerFieldType">text_suggester</str>
<str name="buildOnStartup">false</str>
<str name="highlight">false</str>
</lst>
</searchComponent>
<requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy" >
<lst name="defaults">
<str name="suggest">true</str>
<str name="suggest.count">10</str>
<str name="suggest.dictionary">mySuggester</str>
</lst>
<arr name="components">
<str>suggest</str>
</arr>
</requestHandler>
With the above configuration I am able to get suggestion from Solr. But only
point of confusion is when I repeatedly hit the same search word, results
are coming in different order. Is this an expected pattern with respect to
suggester component. Example for mentioned pattern is given below for
reference
localhost:8983/solr/techproduct/suggest?suggest=true&suggest.build=true&suggest.dictionary=mySuggester&wt=json&suggest.q=lat&suggest.cfq=memory
Sample Result 1
{"responseHeader":{"zkConnected":true,"status":0,"QTime":16},"command":"build","suggest":{"mySuggester":{"lat":{"numFound":3,"suggestions":[{"term":"latest
development in electrification","weight":0,"payload":""},{"term":"latest
development in the area of digital
pdp","weight":0,"payload":""},{"term":"latest technology for
materials","weight":0,"payload":""}]}}}}
Sample Result 2
{"responseHeader":{"zkConnected":true,"status":0,"QTime":14},"command":"build","suggest":{"mySuggester":{"lat":{"numFound":3,"suggestions":[{"term":"latest
development in the area of digital
pdp","weight":0,"payload":""},{"term":"latest technology for
materials","weight":0,"payload":""},{"term":"latest development in
electrification","weight":0,"payload":""}]}}}}
First Suggestion in both the case are different.
Please advice
Thanks,
Arun
