blocks|key|386594|text|返回所有结果从来都不是一个好的选择，因为它的性能会非常慢。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|386595|你能提到你的用例吗？|386596|此外，Solr+rows参数还可以帮助您调优返回结果的数量。|offset|length|386597|然而，我不认为有一种方法可以调优行来返回所有结果。它不接受-1作为值。|386598|因此，您需要为要返回的所有结果设置一个较高的值。|386599|entityMap|0|LINK|mutability|MUTABLE|url|http://wiki.apache.org/solr/CommonQueryParameters#rows^0|0|0|8|4|0|0|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|U|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|V|8|@]|9|@$F|W|G|X|1|Y]]|A|$]]|$1|H|3|I|5|6|7|Z|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|10|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|11|8|@]|9|@]|A|$]]]|M|$N|$5|O|P|Q|A|$R|S]]]]

Returning all the results is never a good option as It would be very slow in performance. 
Can you mention your use case ?

Also, Solr <a href="http://wiki.apache.org/solr/CommonQueryParameters#rows">rows</a> parameter helps you to tune the number of the results to be returned. 
However, I don't think there is a way to tune rows to return all results. It doesn't take a -1 as value. 
So you would need to set a high value for all the results to be returned.

blocks|key|386710|text|您应该做的是首先创建一个SolrQuery，如下所示，并设置要批量获取的文档数。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|386711|int+lastResult=0;+//this+is+for+processing+the+future+batch

What you should do is to first create a SolrQuery shown below and set the number of documents you want to fetch in a batch.

<pre><code>int lastResult=0; //this is for processing the future batch

String query = "id:[ lastResult TO *]"; // just considering id for the sake of simplicity

SolrQuery solrQuery = new SolrQuery(query).setRows(500); //setRows will set the required batch, you can change this to whatever size you want.

SolrDocumentList results = solrClient.query(solrQuery).getResults(); //execute this statement
</code></pre>

Here I am considering an example of search by id, you can replace it with any of your parameter to search upon. 

The "lastResult" is the variable you can change after execution of the first 500 records(500 is the batch size) and set it to the last id got from the results. 

This will help you execute the next batch starting with last result from previous batch.

Hope this helps. Shoot up a comment below if you need any clarification.

blocks|key|386802|text|正如其他答案所指出的，您可以将行配置为最大整数，以返回查询的所有结果。不过，我建议使用Solr+feature+of+pagination，并构建一个使用cursorMark应用程序接口为您返回所有结果的函数。它的要点是将cursorMark参数设置为'*'，设置页面大小(rows参数)，并在每个结果上获得下一个页面的cursorMark，因此只使用上一个结果中给定的cursorMark执行相同的查询。通过这种方式，您将以更高的性能更灵活地决定您想要返回多少结果。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|386803|entityMap|0|LINK|mutability|MUTABLE|url|https://cwiki.apache.org/confluence/display/solr/Pagination%2Bof%2BResults^0|17|Q|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

As the other answers pointed out, you can configure the rows to be max integer to yield back all the results for a query.
I would recommend though to use <a href="https://cwiki.apache.org/confluence/display/solr/Pagination+of+Results" rel="nofollow">Solr feature of pagination</a>, and build a function that will return for you all the results using the cursorMark API. The gist of it is you set the cursorMark parameter to '*', you set the page size(rows parameter), and on each result you'll get a cursorMark for the next page, so you execute the same query only with the cursorMark given from the last result. This way you'll have more flexibility on how much of the results you want back, in a much more performant way.

blocks|key|386876|text|我处理这个问题的方法是运行查询两次：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|386877|//+Start+with+your+(usually+small)+default+page+size
solrQuery.setRows(50);+
QueryResponse+response+=+solrResponse(query);
if+(response.getResults().getNumFound()+>+50)+{
++++solrQuery.setRows(response.getResults().getNumFound());+
++++response+=+solrResponse(query);
}|code-block|syntax|javascript|386878|它对Solr进行了两次调用，但是得到了与records....with匹配的很小的性能损失。|386879|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

The way I dealt with the problem is by running the query twice:

<pre><code>// Start with your (usually small) default page size
solrQuery.setRows(50); 
QueryResponse response = solrResponse(query);
if (response.getResults().getNumFound() &gt; 50) {
 solrQuery.setRows(response.getResults().getNumFound()); 
 response = solrResponse(query);
}
</code></pre>

It makes a call twice to Solr, but gets you all matching records....with the small performance penalty.

I executed some query like <code>"Address:Jack*"</code>. It show <code>numFound = 5214</code> and display 100 documents in results page(I changed default display results from 10 to 100).

How can I get all documents.

How to get all results from solr query?

我执行了一些查询，比如"Address:Jack*"。它显示numFound = 5214并在结果页中显示100个文档(我将默认显示结果从10更改为100)。如何获取所有文档。
