Handle expression in the index

I'm starting with Lucene 4 and have built my own analyzer with stemming and synonyms. This works perfectly. I built a Lucene index with several documents (with an ID) containing a text (with TextField) and a list of words or expressions related to the text (a kind of tag). Everything is OK

Re: Handle expression in the index

Re: Setting Similarity classes in Benchmark .alg scripts

testing whether a field has terms before adding document to Index

Hello, I have an application where a great many documents may not have any terms after StandardAnalyzer has had its way with the body. In that case, depending on some other metadata, I may not wish to add the document to the index altogether. Is there a way to tell? i.e., current I'm doing this:
