I have configured NGram Indexing for some fields.
Say I search for the city Ludlow, I get the results (normal search)
If I search for Ludlo (with w ommitted) I get the results
If I search for Ludl (with ow ommitted) I still get the results
I know that they are all partial strings of the main string hence NGram works
perfect.
But when I type in Ludlwo (misspelt, characters o and w interchanged) I dont
get any results, It should ideally match "Ludl" and provide the results.
I am not looking for Edit distance based Spell Correctors. How can I make above
NGram based search work?
Here is my schema.xml (NGramFieldType):
<fieldType name="nGram" class="solr.TextField" positionIncrementGap="100"
stored="false" multiValued="true">
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory"/>
<!-- potentially word delimiter, synonym filter, stop words, NOT stemming -->
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.EdgeNGramFilterFactory" minGramSize="2" maxGramSize="15"
side="front" />
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<!-- potentially word delimiter, synonym filter, stop words, NOT stemming -->
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
