You might also have a look at the MemoryIndex. Question, though, is
what are you hoping to gain from doing a Query against a single
String? Are you doing a FuzzyQuery? You might look at the
SecondString project on SourceForge for doing string comparisons.
I guess I am a bit confused by your problem statement. Perhaps you
can explain more what you are trying to do at a higher level, as it
sounds like to me you have str1 and str2, so why do you need to inject
an index into the middle of it?

I have a use case for comparing two given strings (attached to a

field)
using Lucene and get the similarity scores.
I tried but could not find any built-in way to do so. Hence
assuming that
Lucene only compares a Query against Indexed documents, I came up
with the
following approach:
(Let the 2 strings be, str1 and str2 )
1) Create an IndexWriter using a RAMDirectory (I don't want to store
those
strings on the disk)
2) Index str1 and store it
3) Search str2 in the index. ( shall the indexWriter be closed
before you
search on the index? )
4) Get the similarity score & publish it
5) Delete str1 from the index and make the index available for a new
comparison
Any comments & suggestions on making the process optimal
