Hej!
\nI dag skal vi tale om s\u00f8gemotoren Elasticsearch (herefter ES), som
\narbejder med platformen Docsvision 5.5.<\/p>\n

\"Introduktion
\n
\n<\/a><\/noindex><\/p>\n

1. Installation<\/h3>\n

\nDen seneste version kan downloades via f\u00f8lgende link: www.elastic.co\/downloads\/elasticsearch<\/a><\/noindex>
\nSk\u00e6rmbillede af installationsprogrammet nedenfor:
\n \"Introduktion
\n<\/p>\n

2. Kontrol af funktionsdygtighed<\/h3>\n

\nEfter installeringen skal du g\u00e5 til adressen
\nhttp:\/\/localhost:9200\/<\/noindex>
\nDer skal vises en side med status for ES, eksempel nedenfor:
\n\"Introduktion<\/p>\n

Hvis siden ikke \u00e5bnes, skal du sikre dig, at Elasticsearch-tjenesten k\u00f8rer. I Windows er dette
\ntjenesten Elasticsearch.
\n\"Introduktion
\n<\/p>\n

3. Tilslutning til Docsvision<\/h3>\n

\nTilslutning til Elasticsearch konfigureres p\u00e5 siden for fuldtekstindeksering.
\n1. Adressen p\u00e5 Elasticsearch-serveren (angivet under installationen).
\n\"Introduktion
\n
\nHer skal angives:
\n2. Forbindelsesstrengen til databasen.
\n3. Adressen til Docsvision (i formatet ConnectAddress=
\nasmxhttp:\/\/SERVER\/DocsVision\/StorageServer\/StorageServerService.
\n4. P\u00e5 fanen \"Kort\" og \"Register\" skal de data, der<\/noindex>)
\nskal indekseres, konfigureres.
\nDu skal ogs\u00e5 sikre dig, at den konto, som Docsvision
\nFulltext Indexing-tjenesten k\u00f8rer under, har adgang til Docsvision-databasen p\u00e5 MS SQL.
\nEfter tilslutningen skal du sikre dig, at der i MS SQL-databasen blev oprettet opgaver med pr\u00e6fikset:
\n\u00abDV:FullText__CardWithFilesPrepareRange\u00bb
\nEfter indstillingerne er blevet konfigureret, vil s\u00f8gefeltet i Windows-klienten blive l\u00e5st op.
\n \"Introduktion
\n
\n4. REST API Elastic<\/p>\n

Administrator kan f\u00e5 forskellige oplysninger om Elasticsearch's drift via<\/h3>\n

\nden tilg\u00e6ngelige REST API.
\nI de f\u00f8lgende eksempler vil vi bruge Insomnia Rest Client.
\nHentning af generelle oplysninger<\/p>\n

N\u00e5r tjenesten er startet og k\u00f8rer (http:\/\/localhost:9200\/ i browseren), kan du<\/h4>\n

\nudf\u00f8re en foresp\u00f8rgsel:
\nVi f\u00e5r svar om status for Elasticsearch (i browseren):
\nhttp:\/\/localhost:9200\/_cat\/health?v<\/noindex><\/p>\n

Statussvar i Insomnia:
\n \"Introduktion
\nBem\u00e6rk, at Status \u2014 Green, Yellow, Red. Den officielle dokumentation siger f\u00f8lgende om statusserne:
\n \"Introduktion
\n\u2022 Green \u2014 Alt fungerer fint (Cluster er fuldt operationelt)
\n\u2022 Yellow \u2014 Alle data er tilg\u00e6ngelige, men nogle replikaer i klusteret er endnu ikke tilg\u00e6ngelige
\n\u2022 Red \u2014 En del data er utilg\u00e6ngelige af en eller anden grund (selve klusteret fungerer normalt)
\nHentning af tilstande om noder i klusteret og deres tilstand (jeg har 1 node):
\nAlle indekser (indices) ES:
\nhttp:\/\/localhost:9200\/_cat\/nodes?v<\/noindex>
\n\"Introduktion
\n
\nUdover indekser fra Docsvision kan der ogs\u00e5 v\u00e6re indekser fra andre applikationer \u2014 heartbeat,
\nhttp:\/\/localhost:9200\/_cat\/indices?v<\/noindex>
\n\"Introduktion
\n
\nkibana \u2014 hvis du bruger dem. N\u00f8dvendige kan sorteres fra de un\u00f8dvendige. For eksempel,
\ntag kun indekser, hvis navn inkluderer rd% i titlen:
\nvi tager kun indekser, der har rd% i navnet:
\nhttp:\/\/localhost:9200\/_cat\/indices\/*card*?v&s=index<\/noindex>
\n \"Introduktion
\n<\/p>\n

Hentning af indstillinger for Elasticsearch: <\/h4>\n

\nHentning af Elasticsearch-indstillinger:
\nhttp:\/\/localhost:9200\/_nodes<\/noindex>
\nResultatet vil v\u00e6re ganske omfattende, inklusive stier til logs:
\n \"Introduktion
\n
\nHvordan man finder listen over indekser, ved vi allerede, Docsvision g\u00f8r dette automatisk ved at give indeksets navn i formatet:
\n<\u0438\u043c\u044f\u0431\u0434+\u0432\u0438\u0434\u0418\u043d\u0434\u0435\u043a\u0441\u0438\u0440\u0443\u0435\u043c\u043e\u0439\u041a\u0430\u0440\u0442\u043e\u0447\u043a\u0438>
\nDet er ogs\u00e5 muligt at oprette en uafh\u00e6ngig indeks:
\nhttp:\/\/localhost:9200\/customer?pretty<\/noindex>
\nDet vil dog ikke v\u00e6re et GET, men en PUT-anmodning:
\n \"Introduktion
\n
\nResultat:
\n \"Introduktion
\n
\nden n\u00e6ste anmodning viser alle indekser, inklusive de nye (customer):
\nhttp:\/\/localhost:9200\/_cat\/indices?v<\/noindex>
\n \"Introduktion
\n<\/p>\n

5. Hentning af information om indekserede data<\/h3>\n

<\/p>\n

Status for Elasticsearch-indekser<\/h4>\n

\nN\u00e5r den oprindelige ops\u00e6tning fra Docsvision er foretaget, skal tjenesten v\u00e6re klar til drift og begynde at indeksere data.
\nF\u00f8rst kan vi tjekke, om indekserne bliver udfyldt, og deres st\u00f8rrelse er st\u00f8rre end standard 'bytes' med den allerede kendte foresp\u00f8rgsel:
\nhttp:\/\/localhost:9200\/_cat\/indices?v<\/noindex>
\nresultatet viser: 87 'opgaver' og 72 'dokumenter' er blevet indekseret, hvis vi taler i termerne af vores EDMS:
\n \"Introduktion
\n
\nEfter noget tid ser resultaterne s\u00e5dan ud (som standard k\u00f8rer jobindekseringen hvert 5. minut):
\n\"Introduktion
\n
\nVi kan se, at antallet af dokumenter er steget.<\/p>\n

Hvordan kan man forst\u00e5, at den n\u00f8dvendige kortl\u00e6gning er blevet indekseret?<\/h4>\n

\u2022 For det f\u00f8rste skal vi sikre os, at korttyperne i Docsvision svarer til de angivne data i Elasticsearch-indstillingerne.
\n\u2022 For det andet skal vi vente p\u00e5, at et s\u00e6t af kort bliver indekseret \u2014 der skal g\u00e5 noget tid, efter at de er kommet ind i Docsvision, f\u00f8r dataene vises i opbevaringen.
\n\u2022 For det tredje kan man s\u00f8ge efter kortet ved hj\u00e6lp af CardID. Dette kan g\u00f8res med anmodningen: <\/p>\n

http:\/\/localhost:9200\/_search?q=_id=2116C498-9D34-44C9-99B0-CE89465637C9<\/noindex><\/p>\n

Hvis kortet er i opbevaringen, vil vi se dets 'r\u00e5' data; hvis ikke, vil vi se et svar som dette:
\n\"Introduktion
\n<\/p>\n

S\u00f8gning efter kortet i Elasticsearch-noden<\/h4>\n

\nFind dokumentet ved pr\u00e6cist at matche feltet Beskrivelse:
\nhttp:\/\/localhost:9200\/_search?q=description: Udg\u00e5ende tv1<\/noindex>
\nResultat:
\n \"Introduktion
\n
\ns\u00f8ger dokumentet, hvor Description indeholder 'Indg\u00e5ende'
\nhttp:\/\/localhost:9200\/_search?q=description like Indg\u00e5ende<\/noindex>
\nResultat:
\n \"Introduktion
\n
\nS\u00f8g efter kortet baseret p\u00e5 indholdet af den vedh\u00e6ftede fil
\nhttp:\/\/localhost:9200\/_search?q=content like 'AGILE'<\/noindex>
\n resultat:
\n \"Introduktion
\n
\nLad os finde alle kort af typen dokument:
\nhttp:\/\/localhost:9200\/_search?q=_type:CardDocument<\/noindex><\/p>\n

eller alle kort af typen opgave:
\nhttp:\/\/localhost:9200\/_search?q=_type:CardTask<\/noindex><\/p>\n

Ved at bruge konstruktioner og<\/b> og de parametre, som Elasticsearch giver i form af JSON, kan vi samle en s\u00e5dan anmodning:
\nhttp:\/\/localhost:9200\/_search?q=_type:CardTask and Employee_RoomNumber: Or\u00ebl kontor and Employee_FirstName: Konstantin<\/noindex><\/p>\n

Den vil vise alle kort af typen opgave blandt brugere, hvor FirstName = Konstantin, og der er i Or\u00ebl Kontor.
\nUdover LIKE<\/b> er der ogs\u00e5 andre dokumenterede parametre:
\n unlike, fields, docs, content osv.
\nAlle disse er beskrevet her<\/a><\/noindex>. <\/p>\n

Det var det for i dag! <\/p>\n
