I am using term vector component in solr for building tag cloud. I am also using porter-stem factory for stemming at index and query time both.
The problem is term vector gives shows stemmed words in final output with term frequency. Example :- If I search for the word 'communication' it gives me term frequency of 'commune', but i need communication. I need stemming only for querying not in term vector. How can i stop this ?
You can create a copy field that doesn't have stemming and query that field to generate your tag cloud.
for example, assuming your current field is called my_text, you may have something like this:
First define a new field:
<field name="my_text_2" type="my_text_type_2" indexed="true" stored="false" termVectors="true"/>
Then copy your text to it at write time:
<copyField source="my_text" dest="my_text_2"/>
where my_text_type_2 is the field type where you can set what analyzers you need. It may be a copy of the current field type used for my_text but without the stemming.
