Hi, well, it's at least a consistent behavior :)
Currently we do these collection searches as textual similarity searches. A given value of 200 for iso translates into the sql search string "iso is like %200%" which returns 200 but also 2000, 3200 and the like. One idea of improvement could be to differentiate three cases: 1) a pure numerical value translates into "iso = value" 2) a pure numerical value preceded by a comparison operator (<, >, <=, >=, <>, =) translates into "iso operator value" 3) all other cases like "", "%", "100%" translate into the original search "iso is like %value%" One could do the same for the aperture property. For datetime it would also make sense to have comparison operators. However, here the current behavior is quite reasonable "2013" gives all images taken in 2013 and this simplicity should probably be kept.
