[14.0] [ADD] full_text_search

[paradoxxxzero]

This module provides a simple way to use full-text search functionality in Odoo models.

It is fully based on PostgreSQL full-text search, and adds a new Searchable field that represents the TSVector column in the database that will store the weighted full-text vector. It also adds the full_text matching operator : @@ to odoo domains.

To add this functionality to a model, simply add a Searchable field to the model with the fields you want to search on weighted by their importance: A, B, C, D with A being the most important.

from odoo import fields, models

class YourModel(models.Model):
    _name = 'your.model'

    full_text = fields.Searchable(
        "Full Text",
        fields={
            "name": "A",
            "description": "B",
            "notes": "C",
        },
        dictionary="english",
    )

And add the full_text field to the model's search view (first position is recommended):

<odoo>
    <record id="view_your_model_search" model="ir.ui.view">
        <field name="model">your.model</field>
        <field name="inherit_id" ref="base.view_your_model_search" />
        <field name="arch" type="xml">
            <field name="name" position="before">
                <field name="full_text" operator="@@" />
            </field>
        </field>
    </record>
</odoo>

You can also use the full_text operator in your own code to search for records:

  records = self.env['your.model'].search([('full_text', '@@', 'search query')])

The search query uses the PostgreSQL websearch syntax with additional prefix matching:

• unquoted text will be ANDed (&)
• quoted text will be searched for with followed by operator (<->)
• text around the OR keyword will be ORed (|)
• a dash - will be treated as a negation operator (!)
• every term will be treated as a prefix match (:*)

The results will be sorted by relevance if no other sort order is specified.
