Builds up an index of Entity IDs as keys (IDs extracted with id-fn), and as value a vector with 2 values:
Builds up an index of Entity IDs as keys (IDs extracted with id-fn), and as value a vector with 2 values: - the start index in the text file to start read EDN for the input doc - the length in bytes input doc
(db & _params)
Tries to read the specified pre-parsed database from filesystem. If this cannot be found, creates and persists a new one.
Params: :id-rx-str - Regular expression STRING REPRESENTATION to retrieve unique ID from the data. The second match is used as the ID. The string is used to name the serialized index. NB: Regular expressions is often much faster than parsing and inspecting data! :id-fn - For more complex parsing/indexing, you can supply a function instead of a regular expression. Only do this, if you are certain it's faster than regex! NB: Only the content of the database will be used to name the persisted index. This using different ID functions will overwrite previously persisted indices where :id-fn is also used! :id-name - Convenience parameter - if you just want to supply the name of the ID in the text based data to search for - creates a regex under the hood. Should be used with the next parameter for optimal speed. :id-type - The type of data to store as ID (key) in the index :source-type - If the source-type is different from the ID type to store in the index :index-folder - Folder to persist index in, defaults to system temp folder :index-persist? - Set to false to inhibit storing the index on disk, defaults to true. Will also inhibit the use of previously persisted indices! :filename - .ndnippy input filename (full path) :index-path - Use with .ndnippy file, docs can be index directly by path vector

(index-id & {:keys [filename id-fn]})
This function generates a pseudo unique index ID for the combination of the ID function and the filename.

Queries a single or multiple docs from the database by a single or multiple IDs matching those from the `.nd*` database by `id-fn`. - returns EDN for the matching document.
