There is a database setting that dictates the minimum length of words indexed for fulltext search. Its default setting is 4. Since my setup is run on a shared server along with numerous other websites I cannot go ahead and change it. In the example above you were searching for words which are too short to be indexed. I will discuss with my webhost if they are willing to change the minimum to 3 characters, when your search would return the results you expected. >Obviously, I tried the wrong things. As long as you are looking for words that are at least four characters in length all kinds of possibilities open up. In your case you might be interested in quoted searches. Here are some search examples that illustrate the effect of quoted search strings: 1) Searching for a normal word like "whacked" returns many results. 2) Using a quoted search for "whacked." returns messages where the word is followed by a period. So putting the search string in quotes allows you to search for words or sentences with punctuation. 3) Using a quoted search for "whacked.230" returns one message/thread. So you can actually search for such terms. As explained above the current minimum for fulltext search would prevent you from finding "wac.230", but you won't find that either in the message text using the old archive. 4) Another interesting example is using a quoted search for "analysis for WAC.230". If you use a quoted search for this term it will actually return the only thread where this text occurs. This happens despite the fact that only the first word in the expression is actually indexed by the fulltext index! It seems to me that you cannot do a search like this in the old archives. Here is a short explanation of the search operators that are available when searching the archive at my site: word Word is optional +word Word must be part of the result -word Word must not be part of the result word* Match different word endings "word word" Match whole phrase I hope you will continue to experiment and let me know if you run into further problems, as I am learning quite a bit myself from the problems that you run into!
