fts | Franco Toolkit System

Imagine we have two tables, One named tags and one named texts as follows:

tags table:

Texts table:

I want to search each Text and attach the tags from Tags table to each text. The output will be something like this:

I is like a loop over each text and then loop over each tag and check if that text includes that tag or not using Like statement. However this is not practical. The other method would be using FTS but I am not quite sure how to write its query since for example this query gives me only texts which have those tags

I am using fetch_parallel method to download fits files and want them to be in sequence so that I can plot them using matplotlib but each time I am running the script there is a separate sequence of returned objects meaning if i pass

Would be possible to create SQLite Virtual Table using EF Core context.Database.EnsureCreated()? I would expect something like [Virtual] attribute to the respective model class.

The reason for this question is using free text search (FTS) for SQLite in-memory DB which requires virtual table. I understand that I can use runtime migrations but EnsureCreated() is so neat and convenient.

I have very simple model with two entities related as One-to-One via reference navigation properties:

I am attempting to use the geotools.org library (Version 24) to write a user-defined function to style my GIS map according to an external data source. The documentation for the GeoTools library includes this tantalizing paragraph in the section on Functions:

When a function is used as part of a Style users often want to calculate a value based on the attributes of the Feature being drawn. The Expression PropertyName is used in this fashion to extract values out of a Feature and pass them into the function for evaluation.

This is exactly what I want to do. However, the documentation includes no actual example of how to do this.

I have spent several days trying various permutations of the Function definition, and I get the same result every time: My user-defined function only receives the geometry attribute, not the extra attributes I have specified.

I have verified that everything else works:

1. The features are read correctly from the shapefile
2. The function is actually called
3. The Feature geometry is passed into the function
4. Upon completion, the map is drawn

But I cannot get the Geotools library to pass in the additional Feature properties from the shapefile. Has anyone gotten this working, or can you even point me to an example of where this is used?

My current function definition:

I am using Postgres FTS to implement search. This is my sample tsvector:

So I want to do some fulltext searching, looked up how to do it with sqlite, implemented that and figured it's to slow. So I chose postgresql as I have been using that database anyway in the last years.

I have a pretty simple table + trigger and an index:

I'm pulling json feed from an API with this code:
