how to add Analyzer and Tokenizer in our customfieldtype

Question

I'm trying to implement an analyzer and tokenizer on my created custom field type. Any ideas on how to implement it?

example:- I have created one custom field type like wtbngramscase in solr schema but I want to create a tokenizer and analyzer using c# code, is there any way to implement it?

<fieldType name="wtbngramscase" class="solr.TextField" positionIncrementGap="100" multiValued="false">
<analyzer Type="index">
<tokenizer class="solr.StandardTokenizerFactory" />
<filters class="solr.StopFilterFactory" words="stopwords.txt" ignorecase="true" />
<filters class="solr.EdgeNGramTokenizerFactory" mingramsize="1" maxgramsize="70" />
<filters class="solr.LowerCaseFilterFactory" />
</analyzer>
<analyzer Type="query">
<tokenizer class="solr.StandardTokenizerFactory" />
<filters class="solr.StopFilterFactory" words="stopwords.txt" ignorecase="true" />
<filters class="solr.SynonymFilterFactory" expand="true" ignoreCase="true" synonyms="synonyms.txt" />
<filters class="solr.LowerCaseFilterFactory" />
</analyzer>
</fieldType>

Any help will be greatly appreciated.

Answer 1

The analyzers and tokenizers are defined in the managed-schema file present in the indexname/conf path where all the Solr cores are present (See attached image)

So to add your custom fieldtype, you may create a custom index instead of adding it to existing Sitecore indexes. Navigate to the managed-schema file and include your change.
