How to search in an extended value list
When typing a word the search will score the word that is being written last even if its' only a couple of characters and not a fully composed word. This is called a prefix search were the last composition of written characters gets displayed and scored as they are written.
If you were to write the word "Går" the search will display all matching written characters first and the values with the highest score in a descending order. However an exact definition of the word is recommended since this will display and score every value where that specific word are to be found.
If you were to add a second word, the matching combination of words will get the highest score in this case "Vagnhallen Gårda, Göteborg". But it will also display the words that match the second written word in this case "Göteborg". If you start to write a third word, the search will react and prioritise those characters first in the search.
NOTE: An exact match will get highly scored, however the last written word even if its' only a couple of characters will get the highest score in a search. Only the 100 first values will be displayed in the scroll list, in order to access any other potential values a search will have to be performed according to the description above.
