 Connection Parameters
 ---------------------
 
-``setParams()`` and ``setParam()`` accept:
+``setParams()`` and ``setParam()`` support:
 
 - ``host`` (string, default ``127.0.0.1``)
 - ``port`` (int, default ``9306``)
-- ``socket`` (string|null, default ``null``)
-- ``username`` (string|null, optional)
-- ``password`` (string|null, optional)
-- ``options`` (array, driver-specific client options)
+- ``socket`` (string|null)
+- ``username`` (string|null)
+- ``password`` (string|null)
+- ``charset`` (PDO DSN option)
+- ``options`` (array, driver-specific options)
+
+Notes:
+
+- Setting ``host`` to ``localhost`` is normalized to ``127.0.0.1``.
+- Socket notation like ``unix:/path/to/socket`` is converted to ``socket``.
+
+Escaping and Quoting
+--------------------
+
+Value escaping and quoting are connection-driven.
+
+.. code-block:: php
+
+    <?php
+
+    $quotedText = $conn->quote('hello');      // 'hello'
+    $quotedInt = $conn->quote(42);            // 42
+    $quotedNull = $conn->quote(null);         // null
+    $quotedList = $conn->quote([1, 2, 3]);    // (1,2,3)
+
+For raw SQL fragments, use ``SphinxQL::expr()``.
+
+.. code-block:: php
+
+    <?php
+
+    use Foolz\SphinxQL\SphinxQL;
 
-Strict Validation Notes
------------------------
+    $sql = (new SphinxQL($conn))
+        ->select()
+        ->from('rt')
+        ->option('field_weights', SphinxQL::expr('(title=80, content=35)'))
+        ->compile()
+        ->getCompiled();
 
-The query builder validates critical inputs at runtime in 4.0.
-Prefer explicit values over implicit coercion.
+    // SELECT * FROM rt OPTION field_weights = (title=80, content=35)

+Development Guidelines
+----------------------
 
-All pull requests should follow modern PHP style conventions (PSR-12 compatible formatting).
+- Follow PSR-12 style.
+- Add/update tests for behavior changes.
+- Update docs when public API behavior changes.
 
 Testing
 -------
 
-All pull requests must be accompanied with passing tests and code coverage. The SphinxQL Query Builder uses `PHPUnit <https://github.com/sebastianbergmann/phpunit/>`_ for testing.

 Facets
 ======
+
+``Facet`` builds ``FACET`` clauses for grouped aggregations.
+
+Building a Facet
+----------------
+
+.. code-block:: php
+
+    <?php
+
+    use Foolz\SphinxQL\Facet;
+
+    $facet = (new Facet($conn))
+        ->facet(['gid'])
+        ->orderBy('gid', 'ASC');
+
+Common compiled outputs from tests:
+
+- ``facet(['gid'])`` -> ``FACET gid``
+- ``facet(['gid', 'title', 'content'])`` -> ``FACET gid, title, content``
+- ``facet(['alias' => 'gid'])`` -> ``FACET gid AS alias``
+- ``facetFunction('COUNT', 'gid')`` -> ``FACET COUNT(gid)``
+- ``facetFunction('INTERVAL', ['price', 200, 400, 600, 800])`` -> ``FACET INTERVAL(price,200,400,600,800)``
+
+Using FACET with SELECT
+-----------------------
+
+FACET is returned as an extra result set, so use ``executeBatch()``.
+
+.. code-block:: php
+
+    <?php
+
+    use Foolz\SphinxQL\Facet;
+    use Foolz\SphinxQL\SphinxQL;
+
+    $batch = (new SphinxQL($conn))
+        ->select()
+        ->from('rt')
+        ->facet(
+            (new Facet($conn))
+                ->facet(['gid'])
+                ->orderBy('gid', 'ASC')
+        )
+        ->executeBatch()
+        ->getStored();
+
+    // $batch[0] => SELECT rows
+    // $batch[1] => FACET rows with gid + count(*)
+
+Advanced Facet Options
+----------------------
+
+Add ``BY``:
+
+.. code-block:: php
+
+    $facet = (new Facet($conn))
+        ->facet(['gid', 'title', 'content'])
+        ->by('gid');
+
+Sort by expression:
+
+.. code-block:: php
+
+    $facet = (new Facet($conn))
+        ->facet(['gid', 'title'])
+        ->orderByFunction('COUNT', '*', 'DESC');
+
+Paginate facet rows:
+
+.. code-block:: php
+
+    $facet = (new Facet($conn))
+        ->facet(['gid', 'title'])
+        ->orderByFunction('COUNT', '*', 'DESC')
+        ->limit(5, 5);
+
+Validation Notes
+----------------
+
+``Facet`` throws ``SphinxQLException`` for invalid inputs such as:
+
+- empty ``facet()`` columns
+- invalid order directions
+- invalid ``limit()`` / ``offset()``
+- ``facetFunction()`` without parameters

+MatchBuilder
+============
+
+``MatchBuilder`` helps compose advanced ``MATCH()`` expressions.
+
+Use it directly, or pass a callback to ``SphinxQL::match()``.
+
+Standalone Build
+----------------
+
+.. code-block:: php
+
+    <?php
+
+    use Foolz\SphinxQL\MatchBuilder;
+    use Foolz\SphinxQL\SphinxQL;
+

+        ->match('directly')
+        ->orMatch('lazy')
+        ->compile()
+        ->getCompiled();
+
+    // @content directly | lazy
+
+Inline with Query Builder
+-------------------------
+
+.. code-block:: php
+
+    $rows = (new SphinxQL($conn))
+        ->select()
+        ->from('rt')
+        ->match(function ($m) {
+            $m->field('content')

+              ->orMatch('lazy');
+        })
+        ->execute()
+        ->getStored();
+
+Real Compiled Examples from Tests
+---------------------------------
+
+- ``match('test case')`` -> ``(test case)``
+- ``match('test')->orMatch('case')`` -> ``test | case``
+- ``phrase('test case')`` -> ``"test case"``
+- ``proximity('test case', 5)`` -> ``"test case"~5``
+- ``quorum('this is a test case', 3)`` -> ``"this is a test case"/3``
+- ``field('body', 50)->match('test')`` -> ``@body[50] test``
+- ``ignoreField('title', 'body')->match('test')`` -> ``@!(title,body) test``
+- ``zone(['h3', 'h4'])`` -> ``ZONE:(h3,h4)``
+- ``zonespan('th', 'test')`` -> ``ZONESPAN:(th) test``
+
+Expressions and Escaping
+------------------------
+
+Raw expression bypass:
+
+.. code-block:: php
+
+    use Foolz\SphinxQL\SphinxQL;
+
+    $expr = (new MatchBuilder($sq))
+        ->match(SphinxQL::expr('test|case'))
+        ->compile()
+        ->getCompiled();
+
+    // test|case
+
+Without ``Expression``, special characters are escaped.
