javascript - Filtering in Angular using a slight complex boolean condition -

i struggling filters in angularjs. essentially, have checkbox this:

<div class="col-sm-2" style="text-align: right">     <label for="include-deleted-search" class="control-label">include deleted</label> </div> <div class="col-sm-2">     <input ng-model="search.includedeleted" type="checkbox" id="include-deleted-search"/> </div> 

which trying use filter airlines if (the item in filter deleted, , includedeleted true) or item in filter not deleted.

my table looks this, note { isdeleted: search.includedeleted } filter not working i'd like.

<table class="table table-hover table-striped table-bordered">     <thead>         <tr>             <th>ariline id</th>             <th>airline name</th>             <th>country</th>             <th>telephone</th>             <th>24hr telephone</th>             <th>email address</th>             <th>deleted</th>         </tr>     </thead>     <tr dir-paginate="airline in airlines | filter: { airlinename: search.airlinename||'' } | filter: { country: search.countryname||'' } | filter: { isdeleted: search.includedeleted||!isdeleted }  | itemsperpage: pagesize" current-page="currentpage">         <td>{{ airline.airlineid }}</td>         <td>{{ airline.airlinename }}</td>         <td>{{ airline.country }}</td>         <td>{{ airline.telephonenumber }}</td>         <td>{{ ariline.telephone24hour }}</td>         <td>{{ airline.emailaddress }}</td>         <td>{{ airline.isdeleted }}</td>     </tr> </table> 

how can express filter condition? need write custom filter? else working correctly.

if understand intention correctly, can set expression based on search.includedelted. if it's true, return undefined (assuming isdeleted boolean value) not filter of items, otherwise return false, return falsy:

filter:{isdeleted: search.includedeleted?undefined:false}
