Percolationedit
The percolator allows to register queries against an index, then send percolate requests which include a doc, and get back the queries that match on that doc out of the set of registered queries.
Percolate is a complex but awesome Elasticsearch feature, so be sure to read the {ref_current}/search-percolate.html[official documentation].
Register a Percolatoredit
client.RegisterPercolator<ElasticsearchProject>("my-percolator", p => p
.Query(q => q
.Term(f => f.Name, "NEST")
)
);
Percolate a Documentedit
var project = new ElasticsearchProject
{
Id = 1,
Name = "NEST",
Country = "Netherlands"
};
var result = client.Percolate<ElasticsearchProject>(p => p.Document(project));
result.Matches will contain any percolators that matched the given document project.
Unregister a Percolatoredit
client.UnregisterPercolator<ElasticsearchProject>("my-percolator");
Percolate from a Bulk index actionedit
It’s also possible to percolate while bulk indexing:
client.Bulk(b => b
.Index<ElasticsearchProject>(i => i
.Document(new ElasticsearchProject { Id = 1, Name = "NEST" })
.Percolate("*") // Match on any percolated docs
)
);
