Ignore short/common words when searching for similar ideas
When I type a new idea in the search field, you look for ideas containing what I have typed.... great... however if a user types common words such as "a" or "the" then ideas containing them are also shown to the user even if they are not relevant.
Perhaps consider ignoring words of less than 3 characters?
I think having an inclusive match is a good thing. So what if a search for "a" returns lots of results? Your users are then forced to search using a more meaningful search term, which is a good thing as it makes people switch their brains on and engage with the process. However, what would be great is a search that builds relationships between words based on known variations, so a search for "search" would return ideas with "look" or "find".

ignoring all words with less than three characters is only a short solution as many abbreviations only use three letters and are important to search for. I'd rather have the possibility to have an 'ignore list' in the admin section which is prefilled with the common short binding words like "I, and, the a, we, as, ...". But in order to be compatible with other languages you either should have small dictionary for all languages or offer the admin to maintain his own list.

There's a limited list of common words that should be ignored, so it doesn't have to be all words less than three characters.
