The wildcard query is “constant score” to make it faster, so unfortunately that
means there is no score differentiation between the wildcard matches.
You can simple add the wildcard prefix as a separate query term and boost it:
q=text:carre* text:carre^1.5

Hi,
I hava two records with name_fra field
One with name_fra=”un test CARREAU”
And another one with name_fra=”un test CARRE”
{
"codeBarre": "1",
"name_FRA": "un test CARREAU"
}
{
"codeBarre": "2",
"name_FRA": "un test CARRE"
}
Configuration of these fields are :
<field name="name_FRA" type="text_general" indexed="true" stored="true"
required="false" multiValued="false" />
<field name="codeBarre" type="string" indexed="true" stored="true"
required="true" multiValued="false" />
<field name="text" type="text_general" indexed="true" stored="false"
multiValued="true" />
<copyField source="name_FRA" dest="text"/>
<fieldType name="text_general" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" />
<!-- in this example, we will only use synonyms at query time
<filter class="solr.SynonymFilterFactory" synonyms="index_synonyms.txt"
ignoreCase="true" expand="false"/>
-->
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.ASCIIFoldingFilterFactory"/>
</analyzer>
<analyzer type="query">

When I’m using this query :
http://localhost:8983/solr/cdv_product/select?q=text%3Acarre*&fl=score%2C+*&wt=json&indent=true&debugQuery=true
The result is :
{
"responseHeader":{
"status":0,
"QTime":2,
"params":{
"debugQuery":"true",
"fl":"score, *",
"indent":"true",
"q":"text:carre*",
"wt":"json"}},
"response":{"numFound":2,"start":0,"maxScore":1.0,"docs":[

"codeBarre":"1",

"score":1.0},
{
"codeBarre":"2",
"name_FRA":"un test CARRE",
"_version_":1480150875738472448,
"score":1.0}]
},
"debug":{

The score is the same for both of record. CARREAU record is first and CARRE is
next. I want to place CARRE before CARREAU result because CARRE is an exact
match. Is it possible?
NB : scoring for this query only use querynorm and boosters
In this test :
http://localhost:8983/solr/cdv_product/select?q=text%3Acarre&fl=score%2C*&wt=json&indent=true&debugQuery=true
I have only one record found but the scoring is more complex. Why?
{ "responseHeader":{ "status":0, "QTime":2, "params":{
"debugQuery":"true", "fl":"score,*", "indent":"true",
"q":"text:carre", "wt":"json"}},
"response":{"numFound":1,"start":0,"maxScore":0.53033006,"docs":[ {
"codeBarre":"2", "name_FRA":"un test CARRE",
