US 2022/0335086 A1 · FULL-TEXT INDEXING METHOD AND SYSTEM BASED ON GRAPH DATABASE

Abstract

The present disclosure relates to a full-text indexing method and system based on a graph database. A full-text indexing engine creates an index template, data with a field type being character string in a graph database is synchronized to the full-text indexing engine, the full-text indexing engine creates an index for each piece of character string data according to the index template to obtain a full-text index; the graph database acquires and sends query request information to the full-text indexing engine; the full-text indexing engine acquires a first result set of a query statement according to the full-text index; the graph database performs data scanning on the first result set based on key-value pairs to obtain a second result set. The full-text indexing engine supports conditional filtering of the character string type. Character string data is quickly found in the full-text indexing engine, thereby improving efficiency of data retrieval.

Dependent claims

A full-text indexing method based on a graph database, comprising:

creating an index template in a full-text indexing engine, synchronizing data with a field type being character string in a graph database to the full-text indexing engine, and creating, by the full-text indexing engine, an index for each piece of character string data according to the index template to obtain a full-text index;
and
acquiring, by the graph database, query request information, and sending the query request information to the full-text indexing engine;
acquiring, by the full-text indexing engine, a first result set of a query statement according to the full-text index;
and performing, by the graph database, data scanning on the first result set based on key-value pairs to obtain a second result set, wherein the query request information comprises the query statement.

A full-text indexing system based on a graph database, comprising a client, a graph database, and a full-text indexing engine, and the graph database comprises a graph server, a metadata server, and a storage server;

the metadata server is configured to store connection information and metadata information of the full-text indexing engine;
the client is configured to send query request information to the graph server, wherein the query request information comprises a query statement;
the graph server is configured to acquire the query request information sent by the client, and send the query request information to the full-text indexing engine;
the full-text indexing engine is configured to acquire a first result set of the query statement according to a full-text index and return the first result set to the graph server, wherein an index template is created in the full-text indexing engine in advance, data with a field type being character string in the graph database is synchronized to the full-text indexing engine, and the full-text indexing engine creates an index for each piece of character string data according to the index template to obtain the full-text index;
and
the storage server is configured to acquire the first result set from the graph server, perform data scanning on the first result set based on key-value pairs to obtain a second result set, and return the second result set to the client through the graph server.
