1.Having the next list of filter queries I would like to get some result documents basing on them
filter queries
fq=(name_text_en_us:"microwave") & fq=(name_text_en_us:"with") & fq=(name_text_en_us:"sensor")
Full url:
http://localhost:8983/solr/master/select?_=15231231220790&fq=name_text_en_us:"microwave"&fq=name_text_en_us:"with"&fq=name_text_en_us:"sensor"&indent=on&q=*:*&wt=json
I'm getting empty result.
Unfortunately I can't merge all queries in one and have to use them in a separate way.
2. I understand that since one of the filter queries consists only from a stopword - i.e. word "with" it will be parsed by SOLR as an empty string and basing on that SOLR will filter out all documents and result will be empty.
If I remove such query and leave other - SOLR returns several documents.
If there any way how I can configure SOLR to not take into account filter queries with stopwords and as a result after those get parsed and become an empty string.
In other words I would like SOLR to skip filter queries with empty string and return result basing on other from the list

I have a situation where I need to search from multiple indexes (products and users). Below is a sample query I am using to do that search
http://localhost:9200/_all/_search?q=*wood*
http://localhost:9200/users,products/_search?q=*wood*
With the above API request, it only returns search results for the product index. But if I search using the below API it returns search results for users index
http://localhost:9200/users/_search?q=*wood*
As you can see I am passing same value for "q" parameter. I need to search for both product and users index and check if there is the word "wood" in any attribute in both indexes. How can I achieve this
You can pass multiple index names instead of _all as it will search in other indices that you don't intent to by using the comma seprated index name like
http://localhost:9200/users,products/_search?q=*wood*
Although, _all should also fetch the result from users index which you get when you specify its name, you need to debug why its happening, maybe increase the size param to 1000 as by default Elasticsearch returns only 10 results and it seems in case of _all all the top results coming from products index only.
Im tring to understand the DSL query i needed if i want to make a search from a result set i got. means i have an initial term search, then i want make another query upon the previous result.
lets say i a have 10 documents with a sharing identifier between them, each document has a description field. i want to search first all the documents containing the value 'Hello' in the description and then take their id's, and search the document containing the value 'good by'.
thanks.
No need to execute two queries, you can use filter context that will filter out the results.filter parameter will filter out documents that do not match, and will also not affect the score for matching documents.
Filter context is in effect whenever a query clause is passed to a
filter parameter, such as the filter or must_not parameters in the
bool query, the filter parameter in the constant_score query, or the
filter aggregation.

I have a db of documents. Every document has a property(keyword) called index (noting to do with the elastic index) and a property(keyword) named superIndex. There can be multiple documents with the same index and multiple documents with the same superIndex in the DB, these fields are not unique.
I run a compound query searching free text on the text content of these documents, with sorting, and get the results I want. However, I get many documents having the same index and/or superIndex. Currently I programmatically filter the result list and take only the first result from each index and superIndex. My requirement is that at the end I'm left with the top results from the sort, the first from each index and superIndex.
Can this be done using elastic query. If so how?
Field collapsing allows you to collapse all search results having the same value in a field (e.g. index). (See Elasticsearch Reference: Field Collapsing)
I have multiple queries that need to filter data on elasticsearch. This queries are returning document ids from indexes that match the filter.
However i need to do another operation depending from user selection, to extract/add document unique id's from previous sum of queries with current query. The maximum number of query search is 5.
Is there an option in elastic so it will extract/add document id's from previous query? Right now i am doing this part in PHP with foreach iteration that takes a lot of time.
Edit
Example :
Ok let say we have one query on same index that contains :
{"query":{"bool":{"filter":[{"wildcard":{"182_empanalyzed":"example"}}]}}}
we will need to substract the document ids from the following query on same index :
{"query":{"bool":{"must_not":[{"nested":{"path":"184","query":{"exists":{"field":"184.*"}}}}]}}}
Keep in mind that this queries are example with only one condition in it, there might be more complexes queries with many fields to be searched on in each query. And from each following query there is an option to substract/add documents ids
How can I get the list of terms that elasticsearch matched in each result? I know the highlight contains this but I want to get a list of the terms that were found without manually performing postprocessing on the highlight for each result.
You could use named queries with unique query for each term.
Search result will contain matched queries for each document in result.
