我在elasticsearch中实现了同义词,但现在我遇到了问题。整个字符串在空格上分割,我无法使用"查看所有结果选项"。 这是我的设置。
$indexSettings['analysis']['analyzer'] = array(
'std' => array( // Will allow query 'shoes' to match better than 'shoe' which the stemmed version
'tokenizer' => 'standard',
'char_filter' => 'html_strip', // strip html tags
'filter' => array('standard', 'elision', 'asciifolding', 'lowercase', 'stop', 'length'),
),
'keyword' => array(
'tokenizer' => 'keyword',
'filter' => array('asciifolding', 'lowercase'),
),
'keyword_prefix' => array(
'tokenizer' => 'keyword',
'filter' => array('asciifolding', 'lowercase', 'edge_ngram_front'),
),
'text_prefix' => array(
'tokenizer' => 'standard',
'char_filter' => 'html_strip', // strip html tags
'filter' => array('standard', 'elision', 'asciifolding', 'lowercase', 'stop', 'edge_ngram_front'),
),
'text_suffix' => array(
'tokenizer' => 'standard',
'char_filter' => 'html_strip', // strip html tags
'filter' => array('standard', 'elision', 'asciifolding', 'lowercase', 'stop', 'edge_ngram_back'),
),
'synonym' => array(
'tokenizer' => 'standard',
'type' => 'custom',
'char_filter' => 'html_strip', // strip html tags
'filter' => array('standard','synonym', 'elision', 'asciifolding', 'kstem', 'length','snowball' ,'lowercase', 'stop',)
),
);
$indexSettings['analysis']['filter'] = array(
'edge_ngram_front' => array(
'type' => 'edgeNGram',
'min_gram' => 2,
'max_gram' => 10,
'side' => 'front',
),
'edge_ngram_back' => array(
'type' => 'edgeNGram',
'min_gram' => 2,
'max_gram' => 10,
'side' => 'back',
),
'stop' => array(
'type' => 'stop',
'stopwords' => '_none_',
),
'length' => array(
'type' => 'length',
'min' => 2,
),
'synonym' => array(
'type' => 'synonym',
'expand' => true,
'synonyms_path' => 'synonyms.txt',
),
);
$properties[$key]['analyzer'] = 'synonym';
在下拉列表中,我给出5个结果显示,一个选项查看所有结果。 寻找"抗Ssl样蛋白"我得到这个词q = Anti ssl =""像=""蛋白质=""在锚标签中查看所有结果。可以看到所有结果选项获得完整的单词。
