Can someone help me with this use case:

1. I have to search a string and let's say the search engine(it is not
lucene) found this string in 100,000 documents.  I need to find the top 10
words occurring in this 100000 documents.As the document size is large how
to further index these documents and find the top 10 words

1. I am thinking of using Lucene Ramdirectory or memory indexing and find
the most occurring top 10 words.
2. Is this the right approach , indexing and writing to the disk would be
almost over kill and a user can search any number of times.

Thanks in advance.
