Slicer search recommendation

Hi maan98 

Thank you for reaching out to the Microsoft Fabric Community Forum.

As pointed out by Deku , Power BI does not currently allow modification of the default slicer search behavior from "Contains" to "Starts With".This is a default and non-configurable behavior of the slicer search box and this behavior is not configurable through the standard Power BI interface. 

As a workaound, please try the below solution:

1. Create a table in Power BI with sample search input values.

    SearchText = DATATABLE("Search", STRING, {{"A"}, {"B"}, {"C"}, {"D"}})

2. Add a slicer to a report using the SearchText[Search] column. Do not create any relationship between this table and main data model.

3. Create a calculated column or measure on  main data table
     

 StartsWithMatch =

     VAR Input = SELECTEDVALUE('SearchText'[Search])

 RETURN

 IF(

    NOT(ISBLANK(Input)) &&

    LEFT(MainTable[TextColumn], LEN(Input)) = Input,1,0)

  4. Use this column as a filter (MainTable = 1) in your report.
