Hi Toke, Nearly 30% of the requests are setting facet.limit=200
On 42000 requests the number of time each field is used for faceting is $ grep 'facet=true' select.log | grep -oP 'facet.field=([^&])*' | sort | uniq -c | sort -r 23119 facet.field=category_path 8643 facet.field=EUR_0_price_decimal 5560 facet.field=type_pratique_facet 5560 facet.field=size_facet_facet 5560 facet.field=marque_facet 5560 facet.field=is_marketplace_origin_facet 5560 facet.field=gender_facet 5560 facet.field=color_facet_facet 5560 facet.field=club_facet 5560 facet.field=age_facet 3290 facet.field=durete_facet 3290 facet.field=diametre_roues_facet 169 facet.field=EUR_1_price_decimal 38 facet.field=EUR_4_price_decimal The larger count of unique values for these fields are category_path 3025 marque_facet 2100 size_facet_facet 1400 type_pratique_facet 166 color_facet_facet 165 Here are 2 typical queries : 2017-11-20 10:13:27.585 INFO (qtp592179046-15153) [ x:french] o.a.s.c.S.Request [french] webapp=/solr path=/select params={mm=100%25&facet.field=category_path&facet.field=age_facet&facet.field=is_marketplace_origin_facet&facet.field=type_pratique_facet&facet.field=gender_facet&facet.field=color_facet_facet&facet.field=size_facet_facet&facet.field=EUR_0_price_decimal&facet.field=EUR_0_price_decimal&facet.field=marque_facet&facet.field=club_facet&facet.field=diametre_roues_facet&facet.field=durete_facet&q.alt=*:*& json.nl=map&fl=products_id,product_type_static,name_varchar,store_id,website_id,EUR_0_price_decimal&start=0&fq=(store_id:"1")+AND+(website_id:"1")+AND+(product_status:"1")+AND+(category_id:"3389")+AND+(filter_visibility_int:"2"+OR+filter_visibility_int:"4")&rows=48&bq=is_marketplace_origin_boost_exact:"OUI"^210+is_marketplace_origin_boost:OUI^207+is_marketplace_origin_relative_boost:OUI^203+is_marketplace_origin_boost_exact:"NON"^210+is_marketplace_origin_boost:NON^207+is_marketplace_origin_relative_boost:NON^203+&q=*:*&facet.limit=200&spellcheck.q=&defType=edismax&qf=textSearch&stats=true&facet.mincount=1&facet=true&wt=json&stats.field=EUR_0_price_decimal&stats.field=sort_EUR_0_special_price_decimal&spellcheck.collate=true×tamp=1511172807} hits=953 status=0 QTime=26 2017-11-20 10:17:28.193 INFO (qtp592179046-17115) [ x:french] o.a.s.c.S.Request [french] webapp=/solr path=/select params={mm=100%25&facet.field=category_path&facet.field=age_facet&facet.field=is_marketplace_origin_facet&facet.field=type_pratique_facet&facet.field=gender_facet&facet.field=color_facet_facet&facet.field=size_facet_facet&facet.field=EUR_0_price_decimal&facet.field=marque_facet&facet.field=club_facet& json.nl=map&fl=products_id,product_type_static,name_varchar,store_id,website_id,EUR_0_price_decimal&start=0&fq=(store_id:"1")+AND+(website_id:"1")+AND+(product_status:"1")+AND+(filter_visibility_int:"3"+OR+filter_visibility_int:"4")8&bq=name_boost_exact:"velo"^120+name_boost:"velo"^100+name_relative_boost:velo^80+category_boost:velo^60+is_marketplace_origin_boost_exact:"OUI"^210+is_marketplace_origin_boost:OUI^207+is_marketplace_origin_relative_boost:OUI^203+is_marketplace_origin_boost_exact:"NON"^210+is_marketplace_origin_boost:NON^207+is_marketplace_origin_relative_boost:NON^203+size_facet_boost_exact:"velo"^299+size_facet_boost:velo^296+size_facet_relative_boost:velo^292+marque_boost_exact:"velo"^359+marque_boost:velo^356+marque_relative_boost:velo^352+&q=velo&facet.limit=200&spellcheck.q=velo&defType=edismax&qf=textSearch&stats=true&facet.mincount=1&facet=true&wt=json&stats.field=EUR_0_price_decimal&stats.field=sort_EUR_0_special_price_decimal&spellcheck.collate=true×tamp=1511173047} hits=6761 status=0 QTime=38 Dominique Le sam. 2 déc. 2017 à 16:23, Toke Eskildsen <t...@kb.dk> a écrit : > Dominique Bejean <dominique.bej...@eolya.fr> wrote: > > Hi, Thank you for the explanations about faceting.
