How do you choose t2 and t2a? If you have a full inventory of these pairs, you can make these multi-word synonyms and use the Synonym filter to combine them.

Hi,

I am looking for a token filter that can combine 2 terms into 1? E.g.

the input has been tokenized by white space:

t1 t2 t2a t3

I want a filter that output:

t1 t2t2a t3

I know it is a very special case, and I am thinking about develop a filter
of my own. But I cannot figure out which API I should use to look for terms
in a Token Stream.
