我正在尝试让 Solr SpellCheckComponent 工作，但遇到了一些问题。当我运行 .../solr/collection1/select?q= %3A &wt=json&indent=true
返回这些结果
{
"responseHeader": {
"status": 0,
"QTime": 1,
"params": {
"indent": "true",
"q": "*:*",
"_": "1379457032534",
"wt": "json"
}
},
"response": {
"numFound": 2,
"start": 0,
"docs": [
{
"enterprise_name": "because",
"name": "doc1",
"enterprise_id": "100",
"_version_": 1446463888248799200
},
{
"enterprise_name": "what",
"name": "RZTEST",
"enterprise_id": "102",
"_version_": 1446464432735518700
}
]
}
}
这些是我索引的值。现在，当我想查询拼写时，我得到了一些奇怪的结果。
当我运行 /solr/collection1/select?q=name%3Arxtest&wt=json&indent=true&spellcheck=true
结果是准确的，我得到了
{
"responseHeader":{
"status":0,
"QTime":4,
"params":{
"spellcheck":"true",
"indent":"true",
"q":"name:rxtest",
"wt":"json"}},
"response":{"numFound":0,"start":0,"docs":[]
},
"spellcheck":{
"suggestions":[
"rxtest",{
"numFound":1,
"startOffset":5,
"endOffset":11,
"suggestion":["rztest"]}]}}
每当我运行没有名称值的查询时，我都会得到 0 个结果。/solr/collection1/select?q=enterprise_name%3Abecaus&wt=json&indent=true&spellcheck=true
{
"responseHeader":{
"status":0,
"QTime":5,
"params":{
"spellcheck":"true",
"indent":"true",
"q":"enterprise_name:becaus",
"wt":"json"}},
"response":{"numFound":0,"start":0,"docs":[]
},
"spellcheck":{
"suggestions":[]}}
我的猜测是我的方案有问题，但一切看起来都很好。
