Improve ticker-based searching #162
Description
If in Yoroi end-user to search for a pool whose ticker consists of the letters in a-f range and/or digits, currently you can get all kinds of weird results, and somewhere in the returned list you'll get your desired pool (obviously this does not happen if you are searching by a full pool identifier which is a long string).
The enhancement to the user experience would be to do a check on the length of the search string, if it is 5 characters or less to prioritize the search results so that matches in the ticker (exact matches first, then substrings) are shown earlier, compared to matches somewhere in the hex / bech32 pool ID string. So a search for '000' yields the first few results as pools with tickers 000, 0000 and 00000 and not [1PCT] 1 Percent Pool (v1), [AHL] AHLNET #1, [SION] ANGEL stake pool #2, [MASTR] Masterstake as the first few results returned by Yoroi currently.
Improved ticker-based prioritization is already implemented in some of the other community tools e.g. Adastat.net and Pooltool.io
