Hi Sheldon,

You will need to write a custom query parser. However, the current
queryParser.jj is the right place to start.

You can easily modify this to have a pattern of _LETTER only and _DIGIT
only.
Currently it allows numbers and letters to be combined as a term.

If you have more questions, just ask.

Hi Sheldon,

It was my understanding that you should parse the input text yourself
(since you understand the deeper semantics). When you see "MEM12345"
you can add {"MEM12345", "MEM" and "12345"} into the words to index.
This is similar to converting the words to lowercase or stripping
accents when analyzing a text.


If you wanted to get even more fancy you could create one or more
separate fields for the product codes or fragments of product code.
Your GUI could use them to search on.

Does this make sense?
