When using ideas and feedback, the suggestion match is far too broad. We can be presented with 100+ suggestions, most of which are unrelated to what we're suggesting. It seems to match on individual words so including for example "software" in the suggestion gives us every other suggestion that includes "software".

We're all busy and don't have the time to check every suggestion for something similar, hence end up posting it as new. A better matching algorithm would reduce duplications keeping future suggestions more succinct.
