brief: | i18n.site tsopano imathandizira kusaka kwamalemba athunthu opanda seva.

Nkhaniyi ikuwonetsa kukhazikitsidwa kwaukadaulo waukadaulo wamawu akutsogolo, kuphatikiza indexedDB yopangidwa ndi indexedDB, kusaka kwachiyambi, kukhathamiritsa kwa magawo a mawu komanso kuthandizira zilankhulo zambiri.

Poyerekeza ndi mayankho omwe alipo, kusaka koyera kutsogolo kwa i18n.site ndikocheperako komanso mwachangu, koyenera mawebusayiti ang'onoang'ono ndi apakatikati monga zolemba ndi mabulogu, ndipo amapezeka popanda intaneti.

Kusaka Kolondola Kwa Mawu Athunthu

Chidule Cha Mayankho Osakira Mawu Opanda Seva

Kwa mawebusayiti ang'onoang'ono ndi apakatikati omwe ali ngati zikalata / mabulogu anu, kupanga zolemba zodzipangira nokha ndizolemera kwambiri, ndipo kusaka mawu athunthu kopanda ntchito ndikomwe kofala.

Mayankho osakira mawu opanda seva amagwera m'magulu awiri:

Choyamba, ofanana algolia.com

Ntchito zotere zimafunikira kulipira kutengera kuchuluka kwakusaka, ndipo nthawi zambiri sapezeka kwa ogwiritsa ntchito ku China chifukwa chazovuta monga kutsata tsamba lawebusayiti.

Sichingagwiritsidwe ntchito pa intaneti, sichingagwiritsidwe ntchito pa intaneti, ndipo chili ndi malire aakulu. Nkhaniyi sifotokoza zambiri.

Chachiwiri ndikufufuza mawu athunthu.

Pakadali pano, kusaka kodziwika lunrjs komaliza kumaphatikizapo ElasticLunr.js (kutengera chitukuko lunrjs ).

lunrjs Pali njira ziwiri zopangira ma index, ndipo onse ali ndi zovuta zawo.

1. Mafayilo opangidwa kale

   Chifukwa mlozerawu uli ndi mawu ochokera m'malemba onse, ndi wamkulu mu kukula kwake. Nthawi zonse chikalata chiwonjezedwa kapena kusinthidwa, fayilo yatsopano ya index iyenera kukwezedwa. Idzawonjezera nthawi yodikira ya wogwiritsa ntchito ndikuwononga bandwidth yambiri.

2. Kwezani zikalata ndi kupanga indexes pa ntchentche

   Kupanga index ndi ntchito yovuta kwambiri yomanganso index nthawi iliyonse mukafika kumapangitsa kuti pakhale kusakhazikika komanso kusazindikira bwino kwa ogwiritsa ntchito.

Kuphatikiza pa lunrjs , palinso mayankho ena athunthu, monga :

fusejs , werengerani kufanana pakati pa zingwe kuti mufufuze.

Magwiridwe a yankholi ndiwoyipa kwambiri ndipo sangathe kugwiritsidwa ntchito posaka mawu athunthu (onani Fuse.js Kufunsa kwautali kumatenga kupitilira masekondi 10 , mungakulitsitse bwanji? ).

TinySearch , gwiritsani ntchito fyuluta ya Bloom kuti mufufuze, siingagwiritsidwe ntchito pakusaka kwachiyambi (mwachitsanzo, lowetsani goo , fufuzani good , google ), ndipo simungathe kukwaniritsa zotsatira zofananazo.

Chifukwa cha zolakwika za mayankho omwe alipo, i18n.site adapanga njira yatsopano yosakira mawu, yomwe ili ndi zotsatirazi :

1. Imathandizira kusaka kwa zinenero zambiri ndipo ndi yaying'ono mu kukula kwa kernel yofufuzira pambuyo pa kulongedza gzip ndi 6.9KB (poyerekeza, kukula kwa lunrjs ndi 25KB )
2. Pangani index inverted yochokera ku indexedb , yomwe imatenga kukumbukira pang'ono komanso mwachangu.
3. Zolemba zikawonjezeredwa / kusinthidwa, zolemba zokha zowonjezera kapena zosinthidwa zimasinthidwanso, kuchepetsa kuchuluka kwa mawerengedwe.
4. Imathandizira kusaka kwachiyambi, komwe kumatha kuwonetsa zotsatira zakusaka munthawi yeniyeni pomwe wogwiritsa ntchito akulemba.
5. Ikupezeka Popanda Intaneti

Pansipa, i18n.site tsatanetsatane waukadaulo waukadaulo adzafotokozedwa mwatsatanetsatane.

Kugawa Mawu Azilankhulo Zambiri

Kugawanika kwa mawu kumagwiritsa ntchito gawo la mawu a msakatuli Intl.Segmenter , ndipo asakatuli onse akuluakulu amathandizira mawonekedwe awa.

Mawu akuti segmentation coffeescript code ali motere

SEG = new Intl.Segmenter 0, granularity: "word"

seg = (txt) =>
  r = []
  for {segment} from SEG.segment(txt)
    for i from segment.split('.')
      i = i.trim()
      if i and !'|`'.includes(i) and !/\p{P}/u.test(i)
        r.push i
  r

export default seg

export segqy = (q) =>
  seg q.toLocaleLowerCase()

mu:

• /\p{P}/ ndi mawu okhazikika omwe amafanana ndi zizindikiro zofananira ndi izi: ! " # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \ ] ^ _ { | } ```.

  • split('.') ndi chifukwa Firefox msakatuli segmentation mawu alibe gawo . .

  Kupanga Index

  Matebulo osungira zinthu 5 adapangidwa mu IndexedDB :

  • word mawu : id -
  • doc : id - Document url - Nambala ya mtundu wa Document
  • docWord Mndandanda : id - mawu id
  • prefix : - id
  • rindex : id - Document id : Mndandanda wa manambala a mzere

  Pitani pamndandanda wa chikalata url ndi mtundu ver , ndipo fufuzani ngati chikalatacho chili patebulo doc Ngati sichipezeka, pangani index inverted. Nthawi yomweyo, chotsani index inverted ya zolemba zomwe sizinalowe.

  Mwanjira iyi, kuwonjezereka kwa indexing kumatha kukwaniritsidwa ndipo kuchuluka kwa kuwerengera kumachepetsedwa.

  Kumapeto kwakumapeto, cholozera cholozera chikhoza kuwonetsedwa kuti musachedwe progress + css kwa / yoyamba .

  IndexedDB Yolemba Kwambiri Nthawi Imodzi

  Pulojekitiyi idb kutengera kusungidwa kwa asynchronous kwa IndexedDB

  IndexedDB amawerenga ndikulemba ndi asynchronous. Mukapanga index, zolemba zimayikidwa nthawi imodzi kuti mupange index.

  Kuti mupewe kutayika pang'ono kwa data chifukwa cha kulemba kwapikisano, mutha kulozera ku code coffeescript pansipa ndikuwonjezera ing cache pakati pa kuwerenga ndi kulemba kuti mupewe zolemba zopikisana.

  pusher = =>
    ing = new Map()
    (table, id, val)=>
      id_set = ing.get(id)
      if id_set
        id_set.add val
        return
  
      id_set = new Set([val])
      ing.set id, id_set
      pre = await table.get(id)
      li = pre?.li or []
  
      loop
        to_add = [...id_set]
        li.push(...to_add)
        await table.put({id,li})
        for i from to_add
          id_set.delete i
        if not id_set.size
          ing.delete id
          break
      return
  
  rindexPush = pusher()
  prefixPush = pusher()
  

  Precision Ndi Kumbukirani

  Kusakaku kudzakhala gawo loyamba la mawu osakira omwe alowetsedwa ndi wogwiritsa ntchito.

  Tangoganizani kuti pali mawu N pambuyo pa gawo la mawu pobweretsa zotsatira, zotsatira zomwe zili ndi mawu osakira zidzabwezedwa koyamba, kenako zotsatira zomwe zili ndi N-1 , N-2 ,..., 1 mawu osakira.

  Zotsatira zosaka zomwe zimawonetsedwa koyamba zimatsimikizira kulondola kwa funsolo, ndipo zotsatira zomwe zimayikidwa pambuyo pake (dinani batani lowonjezera) zitsimikizire kuchuluka kwa kukumbukira.

  

  Katundu Pakufunika

  Pofuna kuwongolera liwiro la kuyankha, kusaka kumagwiritsa ntchito jenereta yield kuti akwaniritse zomwe akufuna, ndipo amabwerera nthawi limit zotsatira zikafunsidwa.

  Dziwani kuti nthawi iliyonse mukasakanso pambuyo pa yield , muyenera kutsegulanso funso la IndexedDB .

  Kusaka Kwanthawi Yeniyeni

  Kuti muwonetse zotsatira zakusaka pamene wogwiritsa ntchito akulemba, mwachitsanzo, wor akalowa, mawu omwe ali ndi wor monga words ndi work amawonetsedwa.

  

  Kernel yofufuzira idzagwiritsa ntchito tebulo prefix pa liwu lomaliza pambuyo pa gawo la mawu kuti mupeze mawu onse omwe ali nawo, ndikufufuza motsatizana.

  Ntchito yotsutsana ndi kugwedeza debounce imagwiritsidwanso ntchito pakugwirizanitsa kutsogolo (kukhazikitsidwa motere) kuti achepetse kuchuluka kwa zolowera zomwe zimayambitsa kusaka ndikuchepetsa kuchuluka kwa kuwerengera.

  export default (wait, func) => {
    var timeout;
    return function(...args) {
      clearTimeout(timeout);
      timeout = setTimeout(func.bind(this, ...args), wait);
    };
  }
  

  Ikupezeka Popanda Intaneti

  Gome la ndondomeko silisunga malemba oyambirira, mawu okha, omwe amachepetsa kusungirako.

  Kuwunikira zotsatira kumafuna kuti mutsitsenso mawu oyamba, ndipo kufananitsa service worker kungapewe kufunsidwa mobwerezabwereza.

  Nthawi yomweyo, chifukwa service worker imasunga zolemba zonse, wogwiritsa ntchito akangofufuza, tsamba lonselo, kuphatikiza kusaka, limapezeka popanda intaneti.

  Onetsani Kukhathamiritsa Kwa Zolemba Za MarkDown

  i18n.site 's pure-end-end search solution imakongoletsedwa ndi zolemba MarkDown .

  Mukawonetsa zotsatira zakusaka, dzina lamutu lidzawonetsedwa ndipo mutuwo udzawunikidwa mukadina.

  

  Fotokozerani Mwachidule

  Kusaka kwa mawu otembenuzidwa kumayendetsedwa kumapeto kwenikweni, palibe seva yofunikira. Ndizoyenera kwambiri mawebusayiti ang'onoang'ono komanso apakatikati monga zolemba ndi mabulogu amunthu.

  i18n.site Kusaka kotseguka kodzipangira koyambirira, kocheperako kukula komanso kuyankha mwachangu, kumathetsa zophophonya zakusaka kwapamapeto akutsogolo komanso kumapereka chidziwitso cha ogwiritsa ntchito.
