How to search for something dot something (text.text) ?

The problem is that 1PW8 splits your phrase into separate words at certain boundaries like an uppercase letter, a dot, … and instead of searching for all those words (AND) it searches for every word separately (OR). Furthermore another problem of this kind of search is that searching for partial words doesn’t work too, e. g. I have an item named Openweathermap. Entering wea doesn‘t find the entry. This worked perfectly fine in all previous versions.
AgileBits knows about this problem since the beginning of early access tests but they still haven‘t fixed it.
