**`graphile-search-plugin`** enables auto-generated full-text search condition fields for all `tsvector` columns in PostGraphile v5 schemas.

## Installation

```sh
npm install graphile-search-plugin
```

## Features

- Adds full-text search condition fields for `tsvector` columns
- Uses `websearch_to_tsquery` for natural search syntax
- Automatic `ORDER BY ts_rank(column, tsquery) DESC` relevance ordering (matching V4 behavior)
- Cursor-based pagination remains stable — PostGraphile re-appends unique key columns after the relevance sort
- Works with PostGraphile v5 preset/plugin pipeline

## Usage

### With Preset (Recommended)

```typescript
import { PgSearchPreset } from 'graphile-search-plugin';

const preset = {
  extends: [
    // ... your other presets
    PgSearchPreset({ pgSearchPrefix: 'fullText' }),
  ],
};
```

### With Plugin Directly

```typescript
import { PgSearchPlugin } from 'graphile-search-plugin';

const preset = {
  plugins: [
    PgSearchPlugin({ pgSearchPrefix: 'fullText' }),
  ],
};
```

### GraphQL Query

```graphql
query SearchGoals($search: String!) {
  goals(condition: { fullTextTsv: $search }) {
    nodes {
      id
      title
      description
    }
  }
}
```

## Testing

```sh
# requires a local Postgres available (defaults to postgres/password@localhost:5432)
pnpm --filter graphile-search-plugin test
```
