Description

NGramTokenizer with SynonymFilterFacory doesn't work properly when using Managed-Schema

When using Managed-Schema, it doesn't work properly with the following settings.

managed-schema

<field name="bigram" type="text_bigram" indexed="true" stored="true"/>
<fieldType name="text_bigram" class="solr.TextField" positionIncrementGap="100"
					 autoGeneratePhraseQueries="false">
	<analyzer type="index">
		<tokenizer class="solr.NGramTokenizerFactory" minGramSize="2" maxGramSize="2"/>
		<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
						tokenizerFactory="solr.NGramTokenizerFactory"
						tokenizerFactory.minGramSize="2" tokenizerFactory.maxGramSize="2"
						ignoreCase="true" expand="true"/>
	</analyzer>
</fieldType>

synonyms.txt

ab,ba

expected

querystring => "bigram:ab"
parsedquery => "bigram:ab bigram:ba"

actual

querystring => "bigram:ab"
parsedquery => "bigram:ab"

When using ClassicIndexSchemaFactory, works peroperly.
