Elasticsearch的一个Common Lisp客户端:Eclastic

jopen 9年前

一个Common Lisp客户端用于与 elasticsearch交互。

Fetching a document

Asks the server for a document. If none exists, it still returns an empty document, but a warning is signalled:

(document-by-id *my-documents* "1")    ;; => #<<DOCUMENT> /highway/whatever/1 {10083980C3}>    (handler-case (document-by-id *my-documents* "no-such-doc")    (document-not-found "Sorry, I couldn't find that document"))    ;; => "Sorry, I couldn't find that document"

Searching

The query language will be accessible with native Lisp syntax:

(get* *my-documents*        (new-search (match "adventure" "_all")))    ;; => (#<<DOCUMENT> /highway/whatever/321 {10071F58E3}>  ;;     #<<DOCUMENT> /highway/whatever/412 {10071F5963}>  ;;     #<<DOCUMENT> /highway/whatever/431 {10071F59E3}>)  ;;    (:NUM-HITS 3 :SHARDS (:TOTAL 5 :FAILED 5 :SUCCESSFUL 0)   ;;     :TIMED-OUT NIL :TOOK 3)
