Continuous SharePoint crawling after index reset

With SharePoint 2013 we had to reset the index and then activate it Continuous crawling I'm not sure about the inner workings of this type of crawling. When I look at the crawling logs, full crawling doesn't seem to be complete, and continuous crawling starts every day at 7:00 p.m., as shown below:

Enter the image description here

My questions:
1. Do I have to wait for the full crawl to complete? Or should I turn it off to do a full crawl and when it's done can I turn on continuous crawling?
2. Why does continuous crawling start at 7 p.m. every day? Where can I find this setting?

SQL Server – Does the clustered index order have the same constraints as the search nonclustered index?

I have a table with a lot of data and I want to use the following clustered index:

(account_id, group_id, run_id, page_id, date)

For a non-clustered index, if I were to use WHERE filters that involve account_id, page_id, and date_timeI know the index doesn't work because I don't include it either group_id and run_id. Does this also apply to the use of a clustered index? I often want to make a query in the form:

FROM my_table
WHERE ad_account_id = %d
  AND page_id = %d
  AND date >= DATE(%s)
  AND date <= DATE(%s)

But sometimes I have questions like:

FROM my_table
WHERE ad_account_id = %d
  AND group_id = %d
  AND date >= DATE(%s)
  AND date <= DATE(%s)


FROM my_table
WHERE ad_account_id = %d
  AND group_id = %d
  AND run_id = %d
  AND date >= DATE(%s)
  AND date <= DATE(%s)

It is not obvious whether one of these uses the clustered index after the given value account_id (I'm pretty sure this isn't a full table scan, but I'm not sure even there).

postgresql – MAX (UPPER (area)) cannot be accelerated with a GiST index for the area?

To get the last session, I have to SELECT MAX(UPPER(range)) AS end FROM sessions WHERE session_id = ?. I have a GiST index for (session_id, range). This query is extremely slow and takes almost 30 seconds. I added a normal btree index (session_id, UPPER(range)) and that has reduced it to less than a millisecond, but it seems the index should allow queries at its upper limit. Is there a way to do this with just one index? Am I doing something wrong, either in the query or in the index? Should I use an index type other than GiST?

Use Unity and C # to index properly in Json

If I wanted to index myself price or galleryId in this json file:

"searchId": null,
"listings": ({
    "sid": 0,
    "id": 25,
    "status": 3,
    "art": {
        "sid": 0,
        "artId": 24,
        "token": "v",
        "name": "A",
        "description": "F",
        "width": 18.0000,
        "height": 24.0000,
        "metricWidth": 0.4572,
        "metricHeight": 0.6096,
        "mediaType": "",
        "fullSizeImageUrl": "http",
        "thumbnailImageUrl": "http",
        "artist": {
            "token": null,
            "firstName": "V",
            "lastName": "G",
            "visibleInSearch": false,
            "inventoryVisibleInSearch": false
    "galleryId": 1,
    "price": 1750,
    "listed": "2020-01-18T21:49:41.447"

Would this be the correct syntax?


        for (int i = 0; i < itemData(0)("listings").Count; i++)

         database.Add(new Art(itemData(0)("listings")(i)("galleryId").ToString(), 

postgresql – How do I create an "empty" subindex or an equivalent index in Postgres?

I have a Boolean column that is wrong for> 99.9% of the rows. I need to get all the rows efficiently where this column is true.

What is the best option? Create an index for the column? Create a sub-index where the column is true? But I don't know which rows the subindex would / should contain.

This is not analyzed, but there is a way to do something like: CREATE INDEX mytable_cond ON mytable () WHERE cond = TRUE; ? Where the index literally contains zero rows?

postgresql – Under what conditions can REINDEX INDEX CONCURRENTLY fail in Postgres?

For example, I believe that creating a unique index at the same time may fail if the index is UNIQUE and an ambiguous entry is inserted in the middle of the process.

REINDEX INDEX CONCURRENTLY can fail if you run it on two different indexes in the same table at the same time because some rows are blocked. This has not been documented anywhere. Are there other scenarios where REINDEX INDEX CONCURRENTLY can fail?

dg.differentialgeometrie – Information on the alignment of the index formula on the orbifold

To let $ X $ be a closed orbifold with singularity $ Sigma X $. The singularity is defined as
$$ Sigma X = {(x) | ~ x in X, ~ G_x neq1 }, $$
Where $ G_x $ is the isotropy group.

To the $ u in K_v (TX) $, we have
$$ Ind (u) = (- 1) ^ { dim (X)}+ sum ^ n_ {i = 1} frac {(- 1) ^ { dim ( Sigma_i)}} {m_i}, $$
Where $ { Sigma_iX } $ denotes all components of the singularity set.

Q. I don't understand how to choose the orientations of the singularity set $ Sigma X $. It seems that the formula changes when we reverse the orientation of the singularity.

php – Note: Undefined index: Page in C: xampp

Good night!
I have notifications and cannot resolve and fix these messages.
Someone with good knowledge who can help me. Below is the code snippet:


    $path = $_GET('pagina'); ----ERRO nesta LINHA
    echo $path;     
            if($path('basename') == "importa.php" or $path('basename') .......

I have had this program for a long time and I believe the version update will be given.

Performance – Optimize the position of the chess pieces on an index

This code is used to convert a chess piece position into an index.

A checkerboard figure describes its position with the file a-h (x-axis) and rank 1-8 (y-axis), so this can be represented with indices from 0 to 63.

56 57 58 59 60 61 62 63
48 49 50 51 52 53 54 55
40 41 42 43 44 45 46 47
32 33 34 35 36 37 38 39
24 25 26 27 28 29 30 31
16 17 18 19 20 21 22 23
 8  9 10 11 12 13 14 15
 0  1  2  3  4  5  6  7
 a                    h

The function accepts a string, which is a checkerboard position.

move = "b2"

b2 is index 9

public func getIndex(move:String) -> Int {
  let base:(Int) =  (0,1,2,3,4,5,6,7)
  let rank:(Int) = { $0 * 8 }
  let x:String = move.substring(to: 1)
  let y:String = move.substring(from: 1)
  let v:Int = Int(y) ?? 0
  switch x {
    case "a": return base(0) + rank(v - 1)
    case "b": return base(1) + rank(v - 1)
    case "c": return base(2) + rank(v - 1)
    case "d": return base(3) + rank(v - 1)
    case "e": return base(4) + rank(v - 1)
    case "f": return base(5) + rank(v - 1)
    case "g": return base(6) + rank(v - 1)
    case "h": return base(7) + rank(v - 1)
    default: return 0

Can anyone suggest ways for a faster approach?
