Extend search functionality for Autosuggest component

[MagdalenaLarge]

As IDS Developer
I want to increase the number of characters in Autosuggest component
So that search performed by my users includes all the characters which are after 20 (which is current limit)

Description
IDS Team highlighted to us a need for the different approach in Autosuggest component. The current limit of 20 characters doesn't allow IDS users to perform correct search in the organisation field. As per accessibility guidance, they adding the abbreviations of the organisations at the end of the sting. Based on their UR majority of the users will search by using the abbreviations, but current set up of the component do not allow it especially that the longest string of characters they need is 86.
A new variant of the Autosuggest component would give users flexibility in setting up the parameter determining the length of characters as per their needs within the limit 0-1, where 0.2 = 20 characters and 0.6 = 60 characters.
Number of hits presented to the users will stay the same = 10.

Acceptance Criteria

1. Parameter limiting the number of characters during fuzzy search is editable for the users.
2. User can only set up value between 0-1.
3. Autosuggest search is adjusting the search based on the parameter set up. If parameter is 0.3 only 30 characters is available, but if user changes to 0.5 search will include 50 characters.
4. Documentation how to use this new functionality is added to Service Manual.
