Words in the beginning of a field are ranked higher (NN, NT and NB)
In compound words (only concerns German) the last component has a higher rank.
For example, when searching for screw, the result hexagon screw is weighted higher than screwdriver.
When searching for multiple words, results where these words are in the same order are ranked higher.
Exact word matches receive a higher rank
A search for screw prioritizes the word screw over cylinder screw.
This means that hits with the word screw are listed in the search results before hits with cylinder screw.
In V11 the number of same words in the index reduced the rank. This was removed in V12.
