…e for easy FTS indexing
Add simple attribute support for full text indexing of a subset of columns in table as well as support to change the default tokenizer behavior [for the table. Porting a change that I did in a copy of SQLite.cs for a UWP Japanese dictionary app ~9 years ago that I'm now trying to port to MAUI. Added a bunch of unit tests to cover the functionality and confirmed the existing tests are all passing on Win11.
Example usage:
[FullTextTable]
public class Article
{
[PrimaryKey, AutoIncrement]
public int Id { get; set; }
[FullTextIndexed]
public string Title { get; set; }
[FullTextIndexed]
public string Content { get; set; }
public string Author { get; set; }
public DateTime PublishDate { get; set; }
}
[FullTextTable("JapaneseText_FT", "unicode61")]
public class JapaneseText
{
[PrimaryKey, AutoIncrement]
public int Id { get; set; }
[FullTextIndexed]
public string Text { get; set; }
public string Notes { get; set; }
}

Note that this PR does NOT port custom tokenizer support that I also had added in order to use a Japanese word breaker, but I can work around that with pre-breaking using a .NET Japanese language model library as long as I can at least use the "unicode61" tokenizer instead of the default "simple" one that clobbers most Unicode characters.
