**`graphile-pg-textsearch-plugin`** enables auto-discovered BM25 ranked full-text search for PostGraphile v5 schemas using [pg_textsearch](https://github.com/timescale/pg_textsearch).
20+
21+
## Installation
22+
23+
```sh
24+
npm install graphile-pg-textsearch-plugin
25+
```
26+
27+
## Features
28+
29+
- **Auto-discovery**: Finds all text columns with BM25 indexes automatically — zero configuration
30+
- **Condition fields**: `bm25<Column>` condition inputs accepting `{ query, threshold? }` for BM25 ranked search
31+
- **Score fields**: `bm25<Column>Score` computed fields returning BM25 relevance scores (negative values, more negative = more relevant)
32+
- **OrderBy**: `BM25_<COLUMN>_SCORE_ASC/DESC` enum values for sorting by relevance
33+
- Works with PostGraphile v5 preset/plugin pipeline
34+
35+
## Usage
36+
37+
### With Preset (Recommended)
38+
39+
```typescript
40+
import { Bm25SearchPreset } from 'graphile-pg-textsearch-plugin';
41+
42+
const preset = {
43+
extends: [
44+
// ... your other presets
45+
Bm25SearchPreset(),
46+
],
47+
};
48+
```
49+
50+
### With Plugin Directly
51+
52+
```typescript
53+
import { Bm25CodecPlugin, Bm25SearchPlugin } from 'graphile-pg-textsearch-plugin';
54+
55+
const preset = {
56+
plugins: [
57+
Bm25CodecPlugin,
58+
Bm25SearchPlugin(),
59+
],
60+
};
61+
```
62+
63+
### GraphQL Query
64+
65+
```graphql
66+
query SearchArticles($search: Bm25SearchInput!) {
67+
articles(condition: { bm25Body: $search }) {
68+
nodes {
69+
id
70+
title
71+
body
72+
bm25BodyScore
73+
}
74+
}
75+
}
76+
```
77+
78+
Variables:
79+
80+
```json
81+
{
82+
"search": {
83+
"query": "postgres full text search",
84+
"threshold": -0.5
85+
}
86+
}
87+
```
88+
89+
### OrderBy
90+
91+
```graphql
92+
query SearchArticlesSorted($search: Bm25SearchInput!) {
93+
articles(
94+
condition: { bm25Body: $search }
95+
orderBy: BM25_BODY_SCORE_ASC
96+
) {
97+
nodes {
98+
id
99+
title
100+
bm25BodyScore
101+
}
102+
}
103+
}
104+
```
105+
106+
## Requirements
107+
108+
- PostgreSQL with [pg_textsearch](https://github.com/timescale/pg_textsearch) extension installed
109+
- PostGraphile v5 (rc.5+)
110+
- A BM25 index on the text column(s) you want to search:
111+
112+
```sql
113+
CREATE INDEX articles_body_idx ON articles USING bm25(body)
114+
WITH (text_config='english');
115+
```
116+
117+
## Testing
118+
119+
```sh
120+
# requires pyramation/postgres:17 Docker image with pg_textsearch pre-installed
121+
pnpm --filter graphile-pg-textsearch-plugin test
122+
```
123+
