Re: Search without passing any field
No, it won’t slow down performance, but it might use more disk space for the index. Searching one field is usually faster than searching multiple fields. If it was a lot slower, the tutorial would have warned about that. How large is your index? There are some very large Solr collections. Ours is 26 million docs and it isn’t close to the biggest. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Jul 29, 2018, at 11:15 AM, Renuka Srishti > wrote: > > Yeah, I read that, but it will slow down the performance, as copying all > the fields and put that data in one field.

Re: Search without passing any field
Thanks I got it. Somehow I have to tell about fields to solr, it can't automatically apply search on all indexed fields.

Re: Search without passing any field
You may be doing premature optimization here. Remember the copyTarget is store=false/docValues=false, so you are only actually storing unique tokens and document ids/offsets. I would recommend you start from that, do your first schema, figure out what you are not happy about, evolve it, etc. However, you can also switch to eDismax and name specific fields you want to search with qf parameter. https://lucene.apache.org/solr/guide/7_4/the-extended-dismax-query-parser.html (extension of base query parser). Just remember that the processing of the field depends on the field type. So, with copyField, you were searching everything by that type (probably text). With eDismax, if your field is string, you have to match it exactly. Unless you copyField and process it twice. And so on. You have a lot of options, depending on your use cases. Good luck, Alex.

Re: Search without passing any field
Yeah, I read that, but it will slow down the performance, as copying all the fields and put that data in one field. I think for large index it is not the right way to do. Am I right?

Re: Search without passing any field
Thanks for response, Let me explain with an example. I have following fields : name, description, id, title. These fields have following values: doc1 - name : test description : test and run id : t1 title : abc title doc2 - name : abc description : test and run again id : t2 title : xyz title You can see name and description both contain "test", so my question is if I will query for "test" using "q" parameter without specifying the fields in either "df" or "qf", will it be able to search? Because I tried, and I think you have to mention the fields otherwise it will not work. If I will put "df" and "qf" value as "name", so it will return only doc1, but I want to return both documents when I query "test" (Because description also contains "test"). Will it be possible without configuring the "df" or "qf"? Is there any way to apply search on all fields?

Re: Search without passing any field
What do you want Solr to do in that case? Search all the defined fields? Some of them? Pick randomly? This is like asking "can Solr do what I want without telling it what I want?". You can define df or qf _defaults_ in solrconfig.xml for the request handler, that's what those are for. Then the _user_ doesn't need to specify them. Somebody has to however and defaults are how those are usually done.

Re: Search without passing any field
Solr does need to know what field(s) you want to search. And you can configure all of these things in solrconfig.xml, so the user does not have to provide that. Just remember, unless you really know what you are doing, you should not be exposing Solr directly to the user/browser. Think of it more like a database with another layer between it and user-queries. Otherwise, somebody could delete your whole index, etc. Regards, Alex.
