Hi,
consider the following fieldtype (used for autocompletion):
<fieldType name="edgytext" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true" />
<filter class="solr.PatternReplaceFilterFactory"
pattern="([^a-z])" replacement="" replace="all" />
<filter class="solr.EdgeNGramFilterFactory" minGramSize="1"
maxGramSize="25" />
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true" />
<filter class="solr.PatternReplaceFilterFactory"
pattern="([^a-z])" replacement="" replace="all" />
</analyzer>
</fieldType>
This works fine as long as the query string is a single word. For multiple
words, the ranking is weird though.
Example:
Query String: "Bill Cl"
Result (in that order):
- Clyde Phillips
- Clay Rogers
- Roger Cloud
- Bill Clinton
"Bill Clinton" should have the highest rank in that case.
Has anyone an idea how to to configure this fieldtype to make matches in both
tokens rank higher than those who match in either token?
thanks!
