### Search rules fuel <NoticeTag type="experimental" label="experimental" />

Resolving [search rules](/capabilities/search_rules/overview) during a search costs work, and "fuel" is the budget Meilisearch spends on it. These limits keep rule evaluation from degrading search performance as a rule set grows, which is what allows the feature to scale to tens of thousands of rules.

The defaults suit most rule sets. Raise a limit only if rules stop applying as expected and you have confirmed the relevant budget is the cause. Each of these is available via environment variable only; no CLI flag is available.

#### Maximum counted words

**Environment variable**: `MEILI_EXPERIMENTAL_DSR_FUEL_MAX_COUNTED_WORDS`<br />
**Default value**: `10`<br />
**Expected value**: an integer up to `255`

Maximum number of words from the search query that Meilisearch considers when looking for `conditions.query.words` constraints. Words beyond this count cannot trigger a rule.

#### Maximum active rules

**Environment variable**: `MEILI_EXPERIMENTAL_DSR_FUEL_MAX_ACTIVE_RULES`<br />
**Default value**: `1000`<br />
**Expected value**: an integer up to `4294967295`

Maximum number of active rules whose actions are evaluated for a single search.

#### Maximum pin actions

**Environment variable**: `MEILI_EXPERIMENTAL_DSR_FUEL_MAX_PIN_ACTIONS`<br />
**Default value**: `100`<br />
**Expected value**: an integer up to `4294967295`

Maximum number of pin actions applied to a single search. Raise it if a search legitimately needs more pinned documents than this.

#### Word fuel

**Environment variable**: `MEILI_EXPERIMENTAL_DSR_FUEL_WORD_FUEL`<br />
**Default value**: `4096`<br />
**Expected value**: an integer up to `4294967295`

Maximum number of constraint combinations evaluated when looking for `conditions.query.words` constraints.

### Allow requests to private networks <NoticeTag type="experimental" label="experimental" />

**Environment variable**: `MEILI_EXPERIMENTAL_ALLOWED_IP_NETWORKS`<br />
