I do not get any results for the following query: SELECT * FROM test2

  • 0

I do not get any results for the following query:

"SELECT * FROM test2 WHERE MATCH(txt) AGAINST('hello' IN BOOLEAN MODE)"

while test2 looks like:

id | txt
 1 | ...
 2 | ...
 3 | ...
 4 | ...
.. | ...

txt is 30 characters long (TEXT) and fulltext. I have about 16 records (tiny db) and the word hello is placed almost in every record in txt along with other words. I just wanted to know how full-text search works. So i get zero results and I can’t understand why.

    there are two reasons that you are not getting any results:

    Reason 1: your search word ‘hello’ occurs in too many rows.

    A natural language search interprets
    the search string as a phrase in
    natural human language (a phrase in
    free text). There are no special
    operators. The stopword list applies.
    In addition, words that are present in
    50% or more of the rows are considered
    common and do not match. Full-text
    searches are natural language searches
    if no modifier is given.

    Reason 2: your search word ‘hello’ is on the stop-word list.
    Any word on the stopword list will never match!
