The modulefts1(see alsoFtsTwoandFtsUsage) adds full-text indexing capabilities to SQLite. It is not yet included in the SQLite binary distribution; you can find it in the SQLite CVS tree in theext/fts1directory. Building fts1 fts1 can be built either as a standalone shared library, or ...
FTS5提供了支持全文搜索的虚拟表。换言之，不能对现有表中的列创建全文索引。相反，您可以创建一个FT...

All SQL queries on FTSModel classes will be full-table scans except full-text searches and rowid lookups. If the primary source of the content you are indexing exists in a separate table, you can save some disk space by instructing SQLite to not store an additional copy of the search index...
If no indexing or relation is made (for more about indexing and relations, see below) an entry contains exactly two columns:An id for the entry (uniquely generated or provided by the user): Stored as an INTEGER The json object serialized wih JSON.stringify(): Stored as TEXT(For more ...
Store plain text notes with automatic full-text search and back-reference indexing (i.e. a Zettelkasten) Tooling This repository has three small tools for this schema: a virtual FUSE filesystem written in Rust. an HTTP GUI written in python3 using django. a GTK3 UI in Rust that was writt...
It offers support for a wide range of data types, indexing techniques, and advanced features such as full-text search, JSON support, and geospatial data processing. With a strong emphasis on standards compliance and ACID compliance, PostgreSQL is widely used across various industries for handling ...
Enhance the query planner to permit automatic indexing on FROM-clause subqueries that are implemented by co-routine. Disallow the use of "rowid" in common table expressions. Added the PRAGMA cell_size_check command for better and earlier detection of database file corruption. Added the matchi...
Query, set, or clear the automatic indexing capability. Automatic indexing is enabled by default as of version 3.7.17, but this might change in future releases of SQLite. PRAGMA busy_timeout; PRAGMA busy_timeout = milliseconds;Query or change the setting of the busy timeout. This pragma ...
if there is no WHERE clause term that constraints column c, then terms that constrain columns a and b can be used with the index but not terms that constraint columns d through z. Similarly, no index column will be used (for indexing purposes) that is to the right of a column that is...
