How to combine multiple conditions in filters

Question

I have created a table and a search box. I'm trying to filter the table rows based on the value that user enters in the search box. I'm using angular 4 framework.

When I set the filter conditions individually it works but doesn't works when combined.

Below filter works correctly:

return requests.filter(function(request){
   return request.requestedBy.indexOf(value)> -1;
});

But this doesn't works:

return requests.filter(function(request){
   return request.requestedBy.indexOf(value) + request.client.toLowerCase().indexOf(value)> -1;
}) 

Answer 1

Used OR conditional operator

return requests.filter(function(request){
   return request.requestedBy.toLowerCase().indexOf(value.toLowerCase()) > -1 || request.client.toLowerCase().indexOf(value.toLowerCase()) > -1
});
