Struct SearchFilter 

pub struct SearchFilter {
    pub source: Option<String>,
    pub instance: Option<String>,
    pub kind: Option<String>,
    pub scope: Option<String>,
    pub time_from: Option<i64>,
    pub time_to: Option<i64>,
}

Filter pushed into the SQL candidate-retrieval stage of search_chunks_*.

All fields go into the SQL WHERE clause before LIMIT is applied, so they shape the candidate pool itself — never just trim a pre-built majority pool after the fact. This is the load-bearing fix from BLUEPRINT §17.5 PR-C: with thousands of records from one adapter and a handful from another, post-filter shrinkage can leave the minority adapter’s results empty even when they’re the best match.

Empty filter (all fields None) is a no-op — the original WHERE chunks_fts MATCH ? / WHERE e.model_id = ? is preserved.

Fields

source: Option<String>

Adapter id (e.g. "claude-code", "mem0"). When set, only chunks belonging to records from this adapter survive.

instance: Option<String>

Instance discriminator. Only meaningful when source is also set (the SQL key is (adapter, instance)).

kind: Option<String>

Kind string: "fact" / "preference" / "feedback" / "reference" / "episode" / "skill" / "unknown".

scope: Option<String>

Scope string: "user" / "project" / "session" / "ephemeral".

time_from: Option<i64>

Inclusive lower bound on records.created_at (unix epoch seconds).

time_to: Option<i64>

Inclusive upper bound on records.created_at (unix epoch seconds).

Implementations

impl SearchFilter

pub fn is_empty(&self) -> bool

True when every field is None — caller can skip the JOIN.

Trait Implementations

impl Clone for SearchFilter

fn clone(&self) -> SearchFilter

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SearchFilter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SearchFilter

fn default() -> SearchFilter

Returns the “default value” for a type.

impl PartialEq for SearchFilter

fn eq(&self, other: &SearchFilter) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
