While trying to get familiar with ES I wrote some plugins.
But the tests are showing differences compared to Solr.
But where is the bug, in ES or in Solr?
In ES my query is:
{
"fields": [
"score",
"dctitle",
"dcoa"
],
"explain": true,
"query": {
"bool": {
"must": {
"match": {
"text": {
"query": "einzelhandel",
"boost": 200
}
}
},
"should": {
"match": {
"oa": {
"query": "1",
"boost": 400
}
}
}
}
}
}
And the explain result is:
- _explanation: {
- value: 1.4639825
- description: sum of:
- details: [
- {
- value: 1.2748994
- description: weight(text:einzelhandel^200.0 in 188102) [
PerFieldSimilarity], result of:
- details: [
- {
- value: 1.2748994
- description: score(doc=188102,freq=1.0 = termFreq=1.0 ),
product of:
- details: [
- {
- value: 0.98196113
- description: queryWeight, product of:
- details: [
- {
- value: 200
- description: boost
}
- {
- value: 10.386557
- description: idf(docFreq=50, maxDocs=608275)
}
- {
- value: 0.00047270773
- description: queryNorm
}
]
}
- {
- value: 1.2983196
- description: fieldWeight in 188102, product of:
- details: [
- {
- value: 1
- description: tf(freq=1.0), with freq of:
- details: [
- {
- value: 1
- description: termFreq=1.0
}
]
}
- {
- value: 10.386557
- description: idf(docFreq=50, maxDocs=608275)
}
- {
- value: 0.125
- description: fieldNorm(doc=188102)
}
]
}
]
}
]
}
- {
- value: 0.1890831
- description: ConstantScore(oa:[1 TO 1]^400.0)^400.0, product
of:
- details: [
- {
- value: 400
- description: boost
}
- {
- value: 0.00047270773
- description: queryNorm
}
]
}
]
}
}
The top part looks good to me, but why is ES building from
"should(oa:1^400)" something
like "ConstantScore(oa:[1 TO 1]^400.0)^400.0" which looks like a range
query with double boost of 400?
Is that right?

Bernd
