If you want to write queries that handle all the nuances of natural
language text, I would strongly recommend using a text retrieval
language rather than XPath. Many XQuery implementations have free text
retrieval modules.

Hi Folks,
I want to determine if 'Lec ur' occurs in $text.
A naove solution is this XPath expression:
contains($text, 'Lec ur')
However, that does not take into account many important factors:
1. Perhaps 'Lec ur' occurs, but in $text it is in uppercase
2. Perhaps instead of the ' ' ligature, $text uses 'oe'
3. Perhaps in $text 'Lec ur' is split over two lines and thus is hyphenated
4. Perhaps 'Lec ur' is slightly misspelled in $text and therefore requires fuzzy matching
And there are many other important factors.
Do you have an XPath solution to this problem that takes into account the many important factors?
