Question

我有一个Lucene SpellChecker索引实现，如下所示：

def buildAutoSuggestIndex(path:Path):SpellChecker = {
    val config = new IndexWriterConfig(new CustomAnalyzer())
    val dictionary = new PlainTextDictionary(path)
    val directory = FSDirectory.open(path.getParent)
    val spellChecker = new SpellChecker(directory)
    val jw = new JaroWinklerDistance()
    jw.setThreshold(jaroWinklerThreshold)

    spellChecker.setStringDistance(new JaroWinklerDistance())
    spellChecker.indexDictionary(dictionary, config, true)

    spellChecker
}

我需要更新这些Spellchecker词典，即重新索引新条目，而无需重新索引整个索引。有没有办法更新SpellChecker索引？

Answer 1

$('#example').on( 'search.dt', function (e, settings) { var api = new $.fn.dataTable.Api( settings ); var query = api.search(); if(query === ''){ $('#example tfoot').show(); } else { $('#example tfoot').hide(); } }); var table = $('#example').DataTable();已经避免在这里重新编制索引：

SpellChecker.indexDictionary(...)

如果该术语已被包含，

terms: while ((currentTerm = iter.next()) != null) { String word = currentTerm.utf8ToString(); int len = word.length(); if (len < 3) { continue; // too short we bail but "too long" is fine... } if (!isEmpty) { for (TermsEnum te : termsEnums) { if (te.seekExact(currentTerm)) { continue terms; } } } // ok index the word Document doc = createDocument(word, getMin(len), getMax(len)); writer.addDocument(doc);将返回seelkExact，并且未添加具有该术语的n-gram的文档（false）。

如何在不重新索引的情况下更新Lucene Spellchecker索引？
