Question

I’m using this pattern:

http://localhost:8983/solr/select/?q=hello&wt=json&json.wrf=?&indent=true&hl=true&hl.fl=title

It returns like:

?({
    "response":{"numFound":100,"start":0,"docs":[
        {
            "id":"1234",
            "title":"Something Hello"
            ..
            ..
        },
        ... bla bla, to the end
    ]
})

It is obviously showing 100 records found in header but the items { bla bla... } really are just 10 inside. It is really the 100 item in the Index. IT MUST SHOW REALLY EXACTLY 100.

Is it showing just first 10 item?
What did i miss in the pattern?

Answer 1

100 is the total number of records that Solr found, but by default it only returns 10 at a time.

Try adding &rows=100 to the URL to fetch all 100 results at once.

Edit: In a real app, you probably want to fetch results in pages, so that you don’t run out of memory trying to fetch a zillion results at once. In that case, you combine the start and rows options.

For example to fetch 20 results at a time:

• First request would use &start=0&rows=20

• Second request would use &start=20&rows=20

• … and so on, until you have fetched all the results.

This is similar to using the OFFSET and LIMIT keywords in SQL, if you are familiar with those.
