Laravel TNTsearch custom index creation and usage for large SQL database table - sql

Question

Here is my situation, context, and dilemma.
Situation
I'm fairly new to Laravel and still learning the ropes. I recently installed TNTSearch and Laravel Scout and was able to create a model index using the below config. I created the index using the console command php artisan tntsearch:import "App\Models\Product" and can fuzzy search successfully with App\Models\Product::search($keyword)->get().
config/scout.php
'tntsearch' => [
'storage' => storage_path() . '/index',
'fuzziness' => 'auto',
'fuzzy' => [
'prefix_length' => 2,
'max_expansions' => 50,
'distance' => 4,
],
'asYouType' => true
],
Context
I have an SQL database table with over 30k+ product records segmented per province (Canadian project), and instead of searching the whole index and later filter by market, I’d like to create one index per market and launch a search for a given market. I believe it will speed up the search and avoid returning results which will later be discarded! So basically having one product index file per province (i.e. products_on.index, products_qc.index, ...)
Dilemma/Issue
I am unable to find how to create such an index, have it update automatically and also how to use it. I scoured the Internet for tutorial/guidance and could only find scarce information I can hardly put together. I’d appreciate if someone could point me in the right direction or guide me on how to implement such a thing.
No answer is wrong, and any bits and pieces of information can help me greatly to “get up to speed.”
EDIT (July 30th, 2018):
I still haven't found the answer to my request but the more I search, the more I'm concluding search indexes are "tied" to a model, and it is not possible to have more than one index per model. So I would have to create one model extension per market from the original Listings model (Listings_QC, Listings_ON, ...). Then create an index per markets and search from those (Listings_QC::search(...)).
I'm not keen to create models based on data! Is this a good approach/practice?

Answer 1

RESOLVED !
My inexperience with Laravel search index in general lead me in the wrong direction!
I finally found a document explaining how to use searchBoolean() to search using "and". Modified my config as below to add the searchBoolean:
'tntsearch' => [
'storage' => storage_path() . '/index',
'fuzziness' => 'auto',
'fuzzy' => [
'prefix_length' => 2,
'max_expansions' => 50,
'distance' => 4,
],
'asYouType' => true,
'searchBoolean' => true
],
Then specify the market using the model's method toSearchableArray(), and add the market to any requested seach keyword.
For example, listing search with 'Alsace' for a QC market, I launch the search as
Listings::search('Alsace QC')->get().
Voilà! May help others hitting the same "wall"!
