Our web server logs have percent symbols in the entries. I am able to search for certain logs by using REGEX (e.g. REGEX _raw=\/searchresults.html\?ab\=12345\%abc123). But my users are not REGEX savvy. Is there a way to search for characters like %, etc and not use REGEX?
You should be able to search just for the percent symbol without escaping it. You can use the backslash to escape special characters such as quotes and backslashes.
Searches index blah for all entries with percent signs.
works as well.
Seems to me you can really just search for "%" or "25%", either with or without the quotes. Works for me, at least with the default segmentation settings.
It wouldn't work if you were trying to search a portion of a string between breakers. In your example, searching for "%" should work ok, but "%abc" would not. So just add a wildcard to the search "%abc*".
