Lucene score / Do not take into account user privileges in scoring

[fxp]

When doing search, scoring is based on all search criteria including privileges info (added internally). Making the same query while logged in or not, order of the results may differ due to user privileges (even if all records are public).

// Not logged query
+(_op0:1 _op2:1 _op0:0 _op2:0) +_isTemplate:n
// Logged in query
+(_op0:3 _op2:3 _op0:2 _op2:2 _op0:1 _op2:1 _op0:0 _op2:0 _op0:-1 _op2:-1 _owner:1 _dummy:0) +_isTemplate:n

I suggest to set field boosting to 0 by default for those fields:

 <fieldBoosting>
    <Field name="_op0" boost="0.0F"/>
    <Field name="_op1" boost="0.0F"/>
    <Field name="_op2" boost="0.0F"/>
    <Field name="_dummy" boost="0.0F"/>
    <Field name="_isTemplate" boost="0.0F"/>
    <Field name="_owner" boost="0.0F"/>
  </fieldBoosting>
