queries have a parsing phase. In addition bool to function_score special queries such as or those that do not operate entirely on text, queries for text can be divided into two categories:Entry-based query (term-based Queries)Similar term and fuzzy queries are low-level queries that do not contain the parsing phase (low-level Queries). They operate on a single entry. A query for an entry Foo term searches for an exact

[Elasticsearch] adjacent match (2)-multi-value field, degree of closeness and relevanceMultivalue Fields) Using phrase matching on multi-value fields produces odd behavior: PUT /my_index/groups/1{ "names": [ "John Abraham", "Lincoln Smith"]} Run a phrase query for Abraham Lincoln: GET /my_index/groups/_search{ "query": { "match_phrase": { "names": "Abraham Lincoln" } }} Sur

How does GPGPU OpenCL implement exact string search? 1. Acceleration Method (1) store a small amount of constant data, such as the mode string length and text length, in the private memory of the thread. (2) Save the mode string in the local memory of the GPU, and accelerate the thread's access to the mode
