Multiple search

Hi

Im building an app with a gallery of which have thousand of data. To search for particular item in a column is possible but i need to input multiple data in a search query and should get the result, maybe seperated with a comma or characters.

code used for single search: filter(testalls,startswith(isin_nm,textinput5.text)

where testall is the dataverse table used in gallery, isin_nm is the colowmn to be searched in and textinout5 is text label.

please suggest
