Hi,
I have a document indexed in ES and it has a uriPattern non\_analyzed string
field. When I do this:
curl -XPOST [http://localhost:9200/\_search](http://localhost:9200/_search) -d '{
"query":{
"filtered":{
"query":{
"match\_all":{
```
}
},
"filter":{
"regexp":{
```
"couchbaseDocument.doc.uriPattern":"https\:\/\/github\.com\/.\*"
}
}
}
}
}'
It matches "uriPattern":"[https://github.com/x/y](https://github.com/x/y)" and returns the result.
BUT if I pass the same string to a percolator like this:
curl -XPUT localhost:9200/\_percolator/connectors/githubproject -d '{
"query": {
"regexp": {
"uriPattern": "https\:\/\/github\.com\/.\*",
"flags" : "ALL"
}
}
}'
curl -XGET localhost:9200/connectors/couchbaseDocument/\_percolate -d '{
"doc" : {
"uriPattern" : "[https://github.com/x/y](https://github.com/x/y)"
}
}'
It does not match. I've tested all sorts of escapings and regex queries
with special characters don't seem to work in the context of percolators.
Am I doing something wrong?
Ara.

Anybody? Any idea?
