If we figure out how those work maybe we can bundle them as a custom function?

So split on whitespace and then encapsulate each search term in double quotes.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",539590148,

Thank you for adding the escape_function, but it does not work on my datasette-installation (0.33). I've added the following file to my datasette-dir: `/plugins/sql_functions.py`:

```python
from datasette import hookimpl

def escape_fts_query(query):
    bits = query.split()
    return ' '.join('""{}""'.format(bit.replace('""', '')) for bit in bits)

@hookimpl
def prepare_connection(conn):
    conn.create_function(""escape_fts_query"", 1, escape_fts_query)`
```
It has no effect on the standard queries to the tables though, as they still produce errors when including any characters like '-', '/', '+' or '?'

Does the function only work when using costum queries, where I can include the escape_fts-function explicitly in the sql-query?

PS. I'm calling datasette with --plugins=plugins, and my other plugins work just fine.
PPS. The fts5 virtual table is created with 'sqlite3' like so:

`CREATE VIRTUAL TABLE ""cases_fts"" USING FTS5(
  title,
  subtitle,
  resume,
  suggestion,
  presentation,
  detail = full,
  content_rowid = 'id',
  content = 'cases',
  tokenize='unicode61', 'remove_diacritics 2', 'tokenchars ""-_""'
);`

Thanks!","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",539590148,
