Hello Mikhail,
thanks for fast answer. The problem is, that I want to have the dismax
on child and parent together - to have the filter evaluated together.
I need to have documents:
path: car
type:car
color:red
first_country: CZ
name:seat
path: car\engine
type:engine
power:63KW
path: car\engine\manufacturer
type:manufacturer
name: xx
country:PL
path: car
type:car
color:green
first_country: CZ
name:skoda
path: car\engine
type:engine
power:88KW
path: car\engine\manufacturer
type:manufacturer
name: yy
country:PL
where car is parent document engine is its child a manufacturer is child
of engine and the structure can be deep.
I need to make a query with edismax over fields color, first_country,
power, name, country over parent and all childern.
when I ask then "seat 63 kw" i need to get seat car
the same if I will write only "seat" or only "63kw" or only "xx"
but if I will write "seat 88kw" i expect that i will get no result
I need to return parents in which tree are all the words which I wrote
to query.
How I wrote before my solution was to split the query text and use q:*:*
and for each /word/ in query make
fq={!parent which=type:car}/word//
/
//and edismax with qf=color, first_country, power, name, country
Thank you for your time:)

Hello,
It's hard to get into the problem. but you probably want to have dismax on
child level:
q={!parent ...}{!edismax qf='childF1 childF2' v=$chq}&chq=foo bar
It's usually broken because child query might match parents which is not
allowed. Thus, it's probably can solved by adding +type:child into chq.
IIRC edismax supports lucene syntax.

Hi,
I have a question for which I wasn't able to find a good solution.
I have this structure of documents
A
|\
| \
B \
\
C
\
\
\
D
Document type A has fields id_number, date_from, date_to
Document type C has fields first_name, surname, birthdate
Document type D AND B has fields street_name, house_number, city
I want to find *all parents with block join and edismax*.
The problem is that I have found that possible is find children by parent,
or parent by children.
*I want to find parent by values in parent and in children*. I want to use
edismax with all fields from all documents (id_number, date_from, date_to,
has fields first_name, surname, birthdate,street_name, house_number, city).
I want to write *Hynek* AND *Brojova* AND 14 and I expect that it returns
document A because it found Hynek in surname, Brojova in street and 14 in
house number.
This is easy with {!parent which=type:A}
the problem is, that I'm not able to find by condition 789 AND *Brojova*
where 789 is id_number from type A and Brojova is Street from D.
In short I need to find all parents of tree (parent and childern) in which
are matched all the word which i send to condition
My only solution is to make root type X. Then A will be its child. Then I
can use {!parent which=type:X}.
Than this will work:
http://localhost:8983/solr/demo/select?q=*:*&fq={!parent
which=type:X}brojova*&fq={!parent which=type:X}16&wt=json&
indent=true&defType=edismax&qf=id_number date_from date_to has fields
first_name surname birthdate street_name house_number city&stopwords=true&
lowercaseOperators=true
But I believe it can be solved much better.
