[Koha] Search By Barcode having 1, 2 or 3 digit not working in Koha 3.20 or in 3.22

[Sunil Sharma]

Hello Friends,

I checked both Koha 3.20.x as well as Koha 3.22.x on Debian 8 OS, Zebra
version 2.0.61. My other search is working fine but when I search any
barcode having 1, 2 or 3 digit, the search result page will not reflect
proper search result both in Koha OPAC as well as on Staff-Admin page.

For example, when I search 123 it will give the records having barcode as
1231, 1232, 1233, same as if I will search for barcode 121 then it will
give result for biblio having accession no. 121220, 121121 and so on. Even
these barcodes (121 or 123) are present in Koha.

Any pointers would be of help.
