[Koha] Case for selecting Item types preference in Koha OPAC search module

[Mohankumar K]

My Library is currently implementing Koha 3.14. Library has about 9 lakh
records in its database out of which about 70000 are books and around 5
lakhs are article records (analytic records). When a search is done in
Koha, it retrieves mostly articles and other documents. Books are not
listed at the beginning in the search results (i.e. in the first 20
results) which causes some inconvenience to users. Even in faceted
navigation links shown on the left side on the search results page, books
are listed only if 'Show more' link is selected. Is there any way to
display book item types at the beginning in the OPAC search results?
Pull-down menu like 'Libraries' in the default setup, would be great on the
OPAC home page. For libraries having large collection, this will be a
useful feature.

Any way around would be highly appreciated.

Sincerely,
