 Then copy & paste into FileMaker Advanced's Edit Custom Function window.

Description:

This cf creates an index of the given text value.
I use this cf in a calculated field ( unrelated ) to create an index of the calculated text value. It can be used for a search in a portal field. ( portal has to be filtered with a PatternCount function ).

PatternCount ( "field with index" ; "global search field" ) > 0
and
( if u want to show all records )
IsEmpty ( "global search field" )

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it

Discuss:

There is a typo in your CF, the Parameter uses character number as a Parameter and the calculation uses characternumber.

I think this is not useful in the case, since PatternCount doesn't use index.

@ Unix

PatterCount doesn't use the Filemaker field index, thats true, but this cf create a similar index in a valuelist so PatternCount can only be useful ;-)

Ok, I guess your usage may be not PatternCount,
FilterValues ( "field with index" ; "global search field" ) <> ""
for matching every head of words against search field.

Hello Michael, I love your function.

I was wondering, is there any way to remove the full text and the "*" character at the end, and keep only the index?

All the best,

Alex
