# go-gse-elastic
## Put mapping
```json
"analyzer": {
"gse_analyzer": {
"type": "custom",
"tokenizer": "whitespace",
"filter": ["es_synonym"]
}
}
```
```json
"title": {
"type": "keyword"
},
"title_index": {
"type": "text",
"analyzer": "gse_analyzer"
}
```
## Index
Create a new [client](/es/client.go) by [elastic](https://github.com/olivere/elastic) and config your elasticsearch servers.
```go
func (c *Client) data(m map[string]interface{}) map[string]interface{} {
m["title_index"] = c.seg.CutHtml(m["title"].(string))
m["describe_index"] = c.seg.CutHtml(m["describe"].(string))
m["addr_index"] = c.seg.CutHtml(m["addr"].(string))
return m
}
func (c *Client) Index(m map[string]interface{}) error {
_, err := c.Client.Index().Index(House).
Routing(fmt.Sprintf("%d", m["city_id"])).
Id(m["id"].(string)).
BodyJson(m).Do(c.ctx)
return err
}
```
## Search
```go
// github.com/olivere/elastic/v7
func (c *Client) query(title string, cityId, districtId int64,
page, count int) (int64, []map[string]interface{}, error) {
qry := elastic.NewBoolQuery().Filter(elastic.NewTermQuery("city_id", cityId))
qry.Must(
elastic.NewTermQuery("title_index", c.seg.CutHtml(title)),
)
res, err := c.Client.Search(House).
Query(qry).
IgnoreUnavailable(true).
From(page * count).Size(count).
TrackTotalHits(true).
Do(c.ctx)
if err != nil {
return 0, nil, err
}
results := make([]map[string]interface{}, 0)
for _, r := range res.Hits.Hits {
var data map[string]interface{}
if err := json.Unmarshal(r.Source, &data); err != nil {
return 0, nil, err
}
results = append(results, data)
}
return res.TotalHits(), results, nil
}
```
