Text searches on graph data

A computer-implemented method, comprising:

• receiving, from a client, a request to locate a target string in a graph data stored in a database, the request comprising a declarative graph query configured to query the graph data stored in the database, the graph data including a first vertex, a second vertex, and an edge interconnecting the first vertex and the second vertex, the first vertex representing a first string, the second vertex representing a second string, each of the first string and the second string corresponding to a word and/or a portion of a word, and the first string and the second string forming one or more sentences based at least in part on a structural relationship indicated by the edge interconnecting the first vertex and the second vertex;
• and
• responding to the request by at least identifying, in the graph data stored in the database, a first record of a first sentence including a first string that is a linguistic match for the target string, the linguistic match comprising a derivation and/or a conjugation of the target string.

A non-transitory computer-readable medium storing instructions, which when executed by at least one data processor, result in operations comprising:

• receiving, from a client, a request to locate a target string in a graph data stored in a database, the request comprising a declarative graph query configured to query the graph data stored in the database, the graph data including a first vertex, a second vertex, and an edge interconnecting the first vertex and the second vertex, the first vertex representing a first string, the second vertex representing a second string, each of the first string and the second string corresponding to a word and/or a portion of a word, and the first string and the second string forming one or more sentences based at least in part on a structural relationship indicated by the edge interconnecting the first vertex and the second vertex;
• and
• responding to the request by at least identifying, in the graph data stored in the database, a first record of a first sentence including a first string that is a linguistic match for the target string, the linguistic match comprising a derivation and/or a conjugation of the target string.
