           Summary: Can a text substring search function for LibreOffice
                    Calc be created from the Data Sort filter string
                    capability?
           Product: LibreOffice
           Version: 7.3.7.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: medium
         Component: Calc
          Assignee: [email protected]

Description:
I don't seem to be the only one who wishes there were a substring function
available for use in formulas in LibreOffice Calc.  And I'm decades out of date
as a programmer myself.  But maybe it's a useful observation to point out that
the possibility of such a function seems to be implied by Calc's ability to
search for indicated strings in the entries in a sorted column.  Could that
ability be used to create such a function?

Steps to Reproduce:
1. Look through string functions available, and notice the lack of a
SUBSTR[ING] function.
2. Then sort out a file so as to include the sorting filters in some or all
columns.
3. Click the arrow at the top of a column, and type in the "Search items..."
space the text that you want to test for in the column.

Actual Results:
You can find all rows with entries in that column which contain the
searched-for text.

Expected Results:
It would be nice to have a function to test entries for the desired text, a
function which returns at least TRUE or FALSE for the presence of the text in
each entry, so that you can use those results in a conditional formula -- e.g.,
=if(SUBSTRING(C4)=TRUE,D4*E4,0).


Reproducible: Always

Additional Info:
(This is a request for an enhancement, so I don't think there's any point to
resetting my UserProfile.)
