      Description

      I have two documents:

      {"text":"some text", "lang":"cn"}
      {"text":"more text", "lang":"en"}
      

      And the following query, a simple edismax with a boost on lang:en:

      http://localhost:8983/solr/test/select?wt=xml&q=text&defType=edismax&qf=text&debug=true&boost=if(exists(query($bqlang)),2,1)&bqlang=lang:en
      

      The parsedQuery is now slightly different because of it being wrapped in a FunctionScoreQuery. The problem is the explain for the document, which is:

      0.3971361 = product of:
        1.0 = boost
        0.3971361 = boost(if(exists(query(lang:en,def=0.0)),const(2),const(1)))
      

      Which is now unreadable for complicated queries with many clauses. It should resemble the output of 7.2, which was:

      
      0.36464313 = boost(text:text,if(exists(query(lang:en,def=0.0)),const(2),const(1))), product of:
        0.18232156 = weight(text:text in 0) [SchemaSimilarity], result of:
          0.18232156 = score(doc=0,freq=1.0 = termFreq=1.0
      ), product of:
            0.18232156 = idf, computed as log(1 + (docCount - docFreq + 0.5) / (docFreq + 0.5)) from:
              2.0 = docFreq
              2.0 = docCount
            1.0 = tfNorm, computed as (freq * (k1 + 1)) / (freq + k1 * (1 - b + b * fieldLength / avgFieldLength)) from:
              1.0 = termFreq=1.0
              1.2 = parameter k1
              0.75 = parameter b
              2.0 = avgFieldLength
              2.0 = fieldLength
        2.0 = if(exists(query(lang:en,def=0.0)=0.6931472),const(2),const(1))
      

      This bug was introduced in Solr/Lucene 7.3.
