### Problem Description

TimeSeriesIndexSearcher use the tsidOrd to speed up tsid compare. There is a hidden bug:
The init value of tsidOrd is 0, so it's ok to collect data from beginning. But if collect data from the middle, the tsidOrd has a wrong init value. It will cause the PriorityQueue pop the wrong LeafWalker.

### Steps to Reproduce

Create 2 segments IndexWriter, And the first segment is:
|_tsid|@timestamp|
|  ----  | ----  |
|tsid1|1|
|tsid2|11|
|tsid2|10|
|tsid3|1|

 the second segment is:
|_tsid|timestamp|
|  ----  | ----  |
|tsid1|1|
|tsid2|21|
|tsid2|20|
|tsid3|1|

the query is _tsid : tsid2 OR _tsid : tsid3
the current order is : tsid2/21 -> tsid2/11 -> tsid2/20 -> tsid2/10 -> tsid3/1  -> tsid3/1.
The right order is :  tsid2/21 -> tsid2/20 -> tsid2/11 -> tsid2/10 -> tsid3/1  -> tsid3/1.
The reason is in
```
        boolean shouldPop() throws IOException {
            if (tsidOrd == -1) {
                tsidOrd = tsids.ordValue();
            } else if (tsidOrd != tsids.ordValue()) {
                tsidOrd = tsids.ordValue();
                return true;
            }
            return false;
        }
```
the tsidOrd init value is 0, But the first tsidOrd value of this query is 1. So It pop the second segment unexpected.
