Question

table structure (type : MyISAM)

    user_name              varchar(30)                               
function_type              varchar(30)                                   
function_name              varchar(30)                                   
function_description       text 

FULLTEXT :

KEYNAME:             TYPE:                          FIELD:
PRIMARY BTREE       BTREE                          function_name
full_text           FULLTEXT                       function_description             

AND i have these values on the column “function_description” :

function_description:

akram lofaif 
that is das
akram is blum test
adnan is fine

And when i tried to get back some values like this :

SELECT * FROM functions
     WHERE MATCH (function_description)
     AGAINST ('akram' IN NATURAL LANGUAGE MODE)

it did give back NOTHING !

The documentation for Fulltext Indexes states, that a fulltext search for a word yields no results, if the word appears too often:

A word that matches half of the rows in a table is less likely to
locate relevant documents. In fact, it most likely finds plenty of
irrelevant documents. We all know this happens far too often when we
are trying to find something on the Internet with a search engine. It
is with this reasoning that rows containing the word are assigned a
low semantic value for the particular data set in which they occur. A
given word may reach the 50% threshold in one data set but not
another.

If you’re just trying it out, add some more data to your table, where the word akram is not included, in order to reduce the number of rows identified.

If this should be your production table, you might want to try the BOOLEAN mode, which does not follow the natural language limitation:

SELECT * FROM functions
     WHERE MATCH (function_description)
     AGAINST ('akram' IN BOOLEAN MODE)
