You don't need to index fields several times, you can index is just into one field, and use the different query analyzers just to build the query. We're doing this for authors, for example - if query language says "=author:einstein", the query parser knows this field should be analyzed differently (that is the part of your application logic, of your query language semantics - so it can vary).
The parser will change the 'author' to 'nosynonym_author', this means 'nosynonym_author' analyzer to be used for analysis phase, and after the query has been prepared, we 'simply' change the query field from 'nosynonym_author' into 'author'. Seems complex, but it is actually easy. But it depends on what a query parser you can/want to use.
