Improved EntireWord Search

[iget-master]

This pull request implements a better EntireWord Search that gives more relevance to results that starts with the entire search...

Some cases like this search: Lucas do rio

May not show the result Lucas do Rio Verde as first result in this table:

Lucas do Rio Verde
Bahia dos santos do Brasil (Rio grande do sul)
Do do do do (Rio grande do sul)

In my PR:

• I give a relevance multiplier of 30 to a search LIKE 'lucas do%'. This fix the problem above.
• I added a trim() to search, to avoid blank spaces to causing performance issues.
• Moved $like_comparator variable from filterQueryWithRelevance() to getSearchQuery() method
