Basically you need to pre-process the query and rewrite it in a way you think it should be. Then catch the parse exception if you failed to rewrite the query and display an error message on the screen (something like - This kind of query is not supported, please rephrase your query).

I would like to avoid or auto-correct anything that would lead to a ParseException. For example, I don't think you can get a parse exception from Google--even if you omit a closing quote it looks like it just closes it for you (please correct me if you know otherwise). Does anyone have suggestions on how to accomplish this? I imagine it could require a mix of techniques: - pre-processing the input string (e.g. I currently escape colons) - catching generated exceptions and using the exception info to correct the string and retry the query - a modified QueryParser? The next step is probably to compile a list of all the ways a ParseException can be generated, but I figured I should ask if this idea has any merit first.
