Discussion

The textSearch() function searches a character string for words matching a pattern. The function returns .t. if any words in the string matches the pattern. Characters are compared ignoring case.

If used with an Xdialog form, Alpha Anywhere highlights the words that were found when the data is viewed using a form.

Example

? textsearch("now is the time for all good men", "time AND good")
= .T.

? textsearch("now is the time for all good men", "time AND bad")
= .F.

? textsearch("now is the time for all good men", "im")
= .F.

? textsearch("now is the time for all good men", "*im*")
= .T.

? textsearch("now is the time for all good men", "?now")
= .F.

? textsearch("now is the time for all good men", "*now")
