Erick,
your suggestion worked :
<requestHandler name="/getSimilar" class="solr.SearchHandler">
<lst name="defaults">
<!-- Query settings -->
<str name="title">Hotels Similarity</str>
<str name="defType">edismax</str>
<str name="rows">5</str>
<str name="fl">*,score</str>
<str name="fq">active:true</str>
<str name="echoParams">explicit</str>
<str name="wt">json</str>
<str name="q">{!boost
b=recip(dist(2,0,star_rating,0,$star_rating),1,10,10)}{!boost
b=recip(geodist(lat_lon,$lat,$lon),2,200,20)}{!mlt
qf=name,description,facilities,resort,region,dest_level_2 mintf=1
mindf=5 maxqt=50 v=$master_id}</str>
<!-- Default Similarity Parameters-->
<str name="master_id">0</str>
<str name="star_rating">3</str>
<str name="lat">0</str>
<str name="lon">0</str>
</lst>
</requestHandler>
Yonik, running debugQuery=on i verified that the default were added before,
so basically I can see the default replaced but the one I am sending in the
request param take no effect ( as actually the macro disappeared , replaced
by the default) .
Is maybe because I am inside a block with different query parsers ?
Cheers
