An empty search is almost never a platform failure. It usually means the combination of filters you wrote describes very few people, or nobody.
The three usual causes
The headline is too specific
The headline filter matches literally. Senior Data Engineer & Analytics Lead is a headline that exists, but four people in the world have it.
Try the short form and add several variants instead.
The keywords contradict each other
Chaining lots of ANDs shrinks the universe fast. Every keyword you add
has to appear in the same profile: five technologies joined by AND
will exclude perfectly good candidates who only mention four.
The location is too narrow
It's the filter that trims the most. A mid-sized city plus a specialised profile may simply not have enough candidates; widening to the province or region usually unblocks the search.
The candidates have run out
If the list already existed and “Add more candidates” shows a notice saying there are no more, you've drained that search: every candidate matching those filters is already in your list.
To keep going, change Job Titles, Keywords or location. Any of the three gives the search a universe again.
Which order to loosen in
From least to most damaging to list quality:
- Add headline variants (same role, different name).
- Widen the location one level.
- Swap an
ANDfor anORin the keywords. - Open up the experience ranges.
- Drop keywords that were really just nice-to-haves.
