About filters
Applying filters will limit search results. Leave filters empty to apply all choices in the search. Behind the scenes, filters are AND'ed together.
E.g. if you select two regions, the result MUST contain both regions.
In case there are less than 20 results, a softer approach will be used (except on regions).
About results
The scores are normalised, based upon how many filter match the result.
E.g. if you select "Early Stage", "Series A" and "Series B", and the result has only "Series A", the resulting score will be 33%.
