Hi, Thanks for the mail. I had tried the WIKI.
My doubts remaining were mainly:- 1. If we have synonyms specified and they replace your search keyword with the ones specified wouldn't we face a risk of our original keyword missed out. What i meant is if I have a keyword for search say "agriculture" and I replace it with some synonyms, will I never again be able to search directly for "agriculture". ie suppose I have a document which has the term agriculture and none of the synonyms in it. Will that document be retrieved when i search for agriculture as I have now mapped it to other terms. 2. I am still a bit confused about the interpretation of:- a\=>a => b\=>b a\,a => b\,b abc def rose\, my cap , rose flower Can you pls give a one linere explanation for the above. There are some sample entries in the synonyms.txt 3. If I get some help me with the above 3 it will help me understand the backslash "\" also better. Thanks, Mark.
