如何在Solr中的多值字段中执行搜索？

Question

I'm having dificulties to execute a search in Solr. My Solr has a Multivalued field like this document below:

<int name="id">2166324592435</int>
...others fields
<arr name="Series">
   <str>The Walking Dead<\str>
   <str>Game of Thrones<\str>
<\arr>

The Multivalued field Series has the Tv serie which the document references. In the example above, my document says about The Walking Dead and Game of Thrones. I can have documents with one, two or more series or even no series.

What I want to do is search in Solr. I want to give the series that I want and Solr should returns the documents that says about my query. I tryed but I couldn't do it. I tryed the following:

q=series:The Walking Dead or series:Game of Thrones or ...&wt=json

I think I'm doing wrong. What's the correctly way to do it?

Thanks in advance

Answer 1

尝试这样的事情：
series:("The Walking Dead" OR "Game of Thrones")

Answer 2

In addition to @user1452132 's answer -

When you are searching q=series:The Walking Dead , only the is searched across the series field while the walking dead is search across the default search field.

The query formed would be series:the OR text:(Walking Dead)

You can debug the Query using the debugQuery=on in your request url.

You can use Dismax query handler to make it more manageable.

Answer 3

Use in fq parameter (filter query),

Eg

    name:("Java" OR "Python")
    name:("Java" AND "Web")

    // multivalued fields
    author_ids:(1733 OR 58)
    author_ids:(1733 AND 58)

Solr url encoding:

• ':' become '%3A'
• space become '+'

Thus, you might get a url like this:

http://localhost:8983/solr/xxx/select?q=programming&fq=title%3A ("Java"+AND+"web")&wt=json&indent=true&defType=edismax&qf=title&stopwords=true&lowercaseOperators=true

Answer 4

Depending on what the intent of the search is try the following two searches

series:"The Walking Dead" OR series:"Game of Thorns"

series:(The Walking Dead) OR series:(Game of Thorns)

Please read solr query syntax and the underlying Lucene query syntax

Answer 5

I think your the actual problem is using OR as lowercase. When you do something like that, The or value is searched in defaultTextField . Also don't forget to put quotes if there's a whitespace in your query - and you're looking for an exact match.
