1. The new advanced search view relies on a PRECALCULATED INDEX to get its results very fast
2. It supports searching various fields besides title and description,
   now these are supported: tags, text, textarea, select, selectmultiple,
   more will be added later, so this list may not be up-to-date,
   e.g. we could make image field "advanced searchable" by making it declare its description as the searchable text

1. Declare the fields you wanted to be index searchable as "advanced searchable"
2. Go to search-index Dashboad Tab, purge and click "purge" and "index" to recreate the index
3. Create a menu item to link to the (advnaced) search view and configure in this menu item the appearance/behavior of the search view

NOTE: if you enable "advanced searchable" for more fields, you will need to recreate the index
NOTE: after initial creation, the indexed is updated automatically:

1. every time a published item is saved (new or existing one)
2. every time an existing item version is approved
