Azure Search has an upper limit of 1000 fields per index, even for the top tier. In the default Sitecore indexes, all template fields are added as a field in the index.
In a clean Sitecore installation with WFFM and EXM, there at just below 1000 fields in the core database, and just below 400 fields in the master and web index by default.
This means that ...
Does azure search uses Lucene as search engine?
Azure Search is Microsoft's response to providing a cloud based indexer. It uses Elastic Search as the underlying driver, but the Elastic Search engine is not directly accessible. Currently Azure Search is only accessible using RESTful Web services or the Azure Resource Manager control panel.
I assume ...
The problem is that when you are adding fields and have a bunch of languages, this will create a lot of new fields when "indexallfields" is set to true.
(Each field multiplied by the number of languages) So you quickly get over 1000 fields. And since the 1000 fields is an azure limitation, there is not much sitecore can do about it.
The best way to handle ...
You will need to define a custom model that inherits from SearchResultItem to define the field you want to sort based upon using the Content Search API. So assuming your Date field was called Podcast Date, you would define the following model:
public class PodcastDateSearchItem : SearchResultItem
I fixed this issue. You should use
instead of using
<generalRedirectsSearchConfiguration type="Sitecore.ContentSearch.Azure.CloudIndexConfiguration, Sitecore.ContentSearch.Azure">
Issue was solved by decreasing batch size, for more info you can have a look onto:
This value can be set in Sitecore.ContentSearch.Azure.DefaultIndexConfiguration.config which is living under App_Config/Include. Node name ...
This is a super tough question to answer and could lend itself to a number of viewpoints, making it difficult to choose the "right" answer. That said, I believe that this is an incredibly important question because it sheds light on the fact that local development becomes not so local in cloud deployments.
Additionally, when trying to do local development ...
Crawling (getting data into Azure Search)
On the indexing side of things I was able to achieve this in Sitecore 9 by taking the following steps:
Create a custom index configuration for my customer Index. I didn't want to disrupt the standard out the box indexes.
Defined a computed field that read in a Lat Long from my Sitecore Items. The computed field ...
If you came here because you are using Azure Search on Sitecore 9 and are over 1000 fields, then you can safely set IndexAllFields to false, however at time of writing there is one known issue (ref 229445) preventing Forms from working correctly in 9.0.2 and below. To correctly patch your config:
<sitecore role:require="Standalone or ContentManagement or ...
Ensure that IndexWorker service is updated in the same way as xConnect site was:
Stop IndexWorker windows service.
Disable all SOLR configs in IndexWorker and enable all AzureSearch configs under search role\App_data\jobs\continuous\IndexWorker
Add collection.search connection string to search role\App_data\jobs\continuous\IndexWorker\App_config\...
Enabling Azure Search
To use xConnect and IndexWorker with Azure Search you need to do a couple of things:
Create Azure Search service in your Azure subscription. Copy the service key which will be needed for connection strings.
Disable SOLR configuration files by renaming them, e.g. to *.disabled and enable AzureSearch configuration files by removing *....
The current implementation of Sitecore.ContentSearch API depends on Adobe IFilter v9, which can't be installed in Azure App Service.
At the same time, Azure Search itself supports indexing different document formats (PDFs, DOCX/DOC, XLSX/XLS, PPTX/PPT, MSG etc.) when using Azure Blob Storage + Indexer for it: https://docs.microsoft.com/en-us/azure/search/...
This is a limitation from Azure Search.
If you have this issue for a custom index I recommend you to split the index into multiple indexes to have less than 1000 fields per index.
If you have this issue for a Sitecore index I recommend to investigate what fields can be removed from the Sitecore index.
Azure Search has no built in replication at this time. The Sitecore Azure Search Provider can be pointed to multiple Azure Search instance at once and it will mirror all Create, Update, Delete, requests to those additional instances.
Commit policies are the idea of telling the provider when it will finally commit documents into a persistent state so that if the application was to crash or the computer was to power down that you would be able to still search for those documents in the index when the application was started again. Common policies are to commit by document count, time, ...
Where => q
The q parameter is normally the main query for the request
Filter => fq
"fq" stands for Filter Query.This parameter can be used to specify a query that can be used to restrict the super set of documents that can be returned, without influencing score. It can be very useful for speeding up complex queries since the queries specified with fq ...
I found out that this behavior is related to the introduction of SwitchOnRebuild for Azure Search in Sitecore 9.0.2
As from that version, Sitecore has this feature, and it is turned on by default. Which is nice of course. To verify, check the indexes on your Azure Search app and you will see index names with _secondary after rebuilds.
To know which actual ...
Azure Search does not yet support (or simulate) this functionality.
Best you could do is to reconfigure your CM and build a new index name out, then update the configs on the CDs. Will likely need an AppPool recycle unless you do something tricky, so I hope you have load balancers.
It's a bit ugly at the moment, but getting better...
I recently upgraded from Lucence search to Azure search for one of our client and yes 1000 field limit very annoying thing with Azure search because the default Sitecore installation has that much of fields.
So you can choose two way to handle this -
1.You can set the following setting to false <indexAllFields>true</indexAllFields> in Sitecore....
This is normal behaviour in Sitecore 9.1+ and is not a problem.
You have Sitecore Azure Search switch on rebuild enabled, so it will append a random number to the index name when rebuilding and then switch to using it once the rebuild is complete. It should then delete the old index.
I discovered that if you simply use .Equals() then it will work fine. It will perform a Regex match and find all instances, including items that have multiple values in the multilist field.
var test2 = context.GetQueryable<SBJSearchItem>()
.Where(p => p.Authors.Equals("8292632F-244A-4327-9C66-80DCF98CCAB8"))
Yes, you can use an external index provider by implementing a custom search provider to use in place of the standard Lucene or Solr indexes.
This is made possible by Sitecore providing a number of interfaces and base-classes that developers can extend if they want to create their own provider, allowing you in theory to create any kind of index you like.
Alright, the Sitecore.ContentSearch.Azure.dll file in the CD was not (by default) the same version as in the CM. I copied the CM version to the CD bin folder and it works. (but I have no idea why the default installation puts two different files)
Here is a comparison of the detail of the two dlls,
LEFT: CM version, RIGHT: CD version
You can create your own computed field that uses a PDF library to parse the file contents and store it in the index.
I followed this example: https://jeffdarchuk.com/2017/02/12/search-pdf-content-in-sitecore/
public class IndexPdfContent : IComputedIndexField
public object ComputeFieldValue(IIndexable indexable)
This is solved by specifying a cloudFieldName attribute to the <field> element:
<field fieldName="end date"
You use the "sitecore_web_index" which contains all items of web database. If you want to get just pages, you need to filter results. For example:
string keywords = <keywords entered by user>;
using (var context = ContentSearchManager.GetIndex("sitecore_web_index").CreateSearchContext())
var query = context.GetQueryable<SearchResultItem&...
I realize you are using Azure Search so my answer may not be directly relevant to this, but having more familiarity with Solr I thought I would take a look:
By default, a "TF-IDF" based Scoring Model is used. The basic scoring factors:
tf stands for term frequency - the more ...
