Generate LIKEP
query. The syntax is
text2mm(text[, maxwords])
This function will take a text expression, and produce a list of words
that can be given to LIKER
or LIKEP
to find similar
documents. text2mm
takes an optional second argument which
specifies how many words should be returned. If this is not specified
then 10 words are returned. Most commonly text2mm
will be given the
name of a field. If it is an indirect
field you will need to call
fromfile
as shown below:
SELECT text2mm(fromfile(FILENAME))
FROM DOCUMENTS
WHERE DOCID = 'JT09115' ;
You may also call it as texttomm()
instead of text2mm()
.
