Hongtai: First, many thanks for reporting this in such detail, it really helps and it’s obvious you’ve dug into the problem rather than just thrown it over the wall.
Please go ahead and raise a JIRA Best, Erick On Mar 2, 2020, at 03:45, Hongtai Xue <[email protected]> wrote: Hi, Our team found a strange behavior of solr query parser. In some specific cases, some conditional clauses on unindexed field will be ignored. for query like, q=A:1 OR B:1 OR A:2 OR B:2 if field B is not indexed(but docValues="true"), "B:1" will be lost. but if you write query like, q=A:1 OR A:2 OR B:1 OR B:2, it will work perfect. the only difference of two queries is that they are wrote in different orders. one is ABAB, another is AABB, ■reproduce steps and example explanation you can easily reproduce this problem on a solr collection with _default configset and exampledocs/books.csv data. 1. create a _default collection bin/solr create -c books -s 2 -rf 2 2. post books.csv. bin/post -c books example/exampledocs/books.csv 3. run following query. http://localhost:8983/solr/books/select?q=%2B%28name_str%3AFoundation+OR+cat%3Abook+OR+name_str%3AJhereg+OR+cat%3Acd%29&debug=query I printed query parsing debug information. you can tell "name_str:Foundation" is lost. query: "name_str:Foundation OR cat:book OR name_str:Jhereg OR cat:cd" (please note "Jhereg" is "4a 68 65 72 65 67" and "Foundation" is "46 6f 75 6e 64 61 74 69 6f 6e") -------- "debug":{ "rawquerystring":"+(name_str:Foundation OR cat:book OR name_str:Jhereg OR cat:cd)", "querystring":"+(name_str:Foundation OR cat:book OR name_str:Jhereg OR cat:cd)", "parsedquery":"+(cat:book cat:cd (name_str:[[4a 68 65 72 65 67] TO [4a 68 65 72 65 67]]))", "parsedquery_toString":"+(cat:book cat:cd name_str:[[4a 68 65 72 65 67] TO [4a 68 65 72 65 67]])", "QParser":"LuceneQParser"}} -------- but for query: "name_str:Foundation OR name_str:Jhereg OR cat:book OR cat:cd", everything is OK.
