I'm looking into ArangoSearch for the first time and it looks like a pretty good functionality.
However, in all the tutorials, despite having the ability to tell it to index all fields, one cannot do a 'blind' search across all fields of the document. Like when we look at the example below:
FOR d in myView SEARCH d.text IN ["quick", "brown"] RETURN d
I don't seem to have the ability to just search d entirely without specifying each individual field that I want to include in my search. Is that correct and if so, why is that and are there workarounds? I'm dealing with a lot of different collections with a lot of different fields that can contain a relevant term, it would be a shame if I'd have to tabulate all of them to make an expansive search.

Can someone confirm the behaviour of the Smart search results webpart when using a Smart search filter on a particular field, documentation here, when the index, and the expected results, are compound of multiple page types?
In my scenario I have 2 page types, one is always a child of the other, my hypothetical scenario would be a Folder and File types as an example.
I've configured the index with Pages type and Standard analyzer to include all Folder and File types under the path /MyOS/% on the tree.
The search page, includes the Smart search results webpart and a Smart search filter, a checkbox for the File's field FileIsHidden.
What I'm trying to ascertain is the possibility for the results to include all folders that have a hidden field, as well as the files?
Client has a v8.2 license and now has a requirement similar to this scenario.
Thanks so much for any help in advance.
Firstly what i would do is download the latest version of LUKE, it's a lucene inspector that allows you to run queries, inspect the data, etc.
https://code.google.com/archive/p/luke/downloads
Your search indexes are in the App_Data/Modules/SmartSearch/[SearchName], now i am not sure if LUKE can query 2 indexes as the same time, however you can run hte same query against both and see if it's filtering out results one way or another.
If you are trying to query where a field must be a value, and the other page type does not have the field, it probably is filtered out. What you need to do is use the lucene syntax to say "(classname = 'cms.file' and fileonlyproperty = '' OR classname <> 'cms.file')" so to say.
You'll have to test, but say the class name is cms.file and cms.folder, and the property is FileIsHidden, i think the syntax would be:
+((FieldIsHidden:(true) and classname:('cms.file')) OR (NOT classname:('cms.file'))
But you'll have to test that.
I am currently using the 'search in view results' option in the view control to provide the data set for my view (the reason for this is that the data set to be displayed is fairly complex depending on the user - and I was not able to accomplish this using vector filtering).
The problem I have with it, is that the search is a FT search, and that it does not let you search where a field is an exact match on a string, but rather it does a search where the field contains your string.
Does anyone know of an method where I can search the view for exact data?
Thanks in advance.

If your database is not too big you could use a database.search. It uses an #Formula to get the documents. It might be by a magnitude slower than FT Search
Take a look at this code http://openntf.org/XSnippets.nsf/snippet.xsp?id=build-a-search-query I think it could help you do what you are looking for.
Based on what you want to do, a better option is to create a hidden view with the columns you need to match on. Then search on that view rather then an FTI search.
I am indexing the title field for few products in Solr.
But when I am searching, I am not getting those titles in response.
For eg. I am storing following as title : Baboons Typing Tshirt
But when I am searching following I am not getting any result !!!
1)title:Baboons
2)title:(Baboons Typing Tshirt)
3)title:(Baboons*)
On the otherhand, if I am searching like this, I am getting lot of results
1)title:(Tshirt)
I have indexed many titles containing word Tshirt but I want to search a specific title which is failing..!!
I dont know whether Solr is ignoring first words, or it is doing something random.
My Question is basically: If I have a search title with lots of words, I will like to match it with the title which contains maximum common terms.
How to do it?
Thanks
Solr works like that by itself. You don't have to change anything.
You have to be careful how you set up your fields in schema.xml, i.e. how analysis is done.
You can use Solr's admin > Analysis interface to see how exactly your title field (when indexing) and query (when searching) is processed (tokenized, transformed).
Remember, match, in order to occur, requires identical word (case and everything) on both sides (index & query).
To open your index and see how Solr has actually indexed your data, use Luke.
Searching Magento with fulltext search engine and like method , it will store results in catalogsearch_fulltext table in "data_index" field where it stores value in the format like
each searchable attribute is separated with |.
e.g
3003|Enabled|None||Product name|1.99|yellow|0
here it store sku,status,tax class, product name , price ,color etc etc
It stores all searchable attribute value.
Now the issue is for Configurable product , it will also store the associated products name ,price ,status in the same field like
3003|Enabled|Enabled|Enabled|Enabled|None|None|None|None|Product name|Product name|associted Product name1|associted Product name2|associted Product name3|1.99|2.00|2.99|3.99|yellow|black|yellow|green|0|0|0|0
So what happen is if i search for any word from associated product, it will also list the main configurable product as it has the word in its "data_index" field.
Need some suggestion how can i avoid associated products being included in data_index, So that i can have perfect search result.
thanks
We are looking into our search as well and it has been surprising to see the inefficiencies included in the fulltext table. We have some configurable products as well that have MANY variations and their population in the fulltext search is downright horrendous.
As for solutions, I can only offer my approach to fix the problem (not completed: but rather in the process).
I am extending Magento to include an event listener to the process of indexing the products (Because catalog search indexing is when the fulltext database is populated). Once that process occurs, I am writing my own module to remove duplicate entries from the associated products and also to add the functionality of adding additional search keyword terms as populated from a CSV file.
This should effectively increase search speed dramatically and also return more relevent search results. Because as of now, configurable products are getting "search bias" in the search results.
This isn't so much of an answer as a comment, but it was too lengthy to fit in the comments but I thought this might be beneficial to you. Once I get my module working, if you would like, I can possibly give you directions on how you could implement a similar module yourself.
Hope that helped (if only for moral support in magento's search struggle)
I am using the AdvancedDatabaseCrawler as a base for my search page. I have configured it so that I can search for what I want and it is very fast. The problem is that as soon as you want to do anything with the search results that requires accessing field values the performance goes through the roof.
The main search results part is fine as even if there are 1000 results returned from the search I am only showing 10 or 20 results per page which means I only have to retrieve 10 or 20 items. However in the sidebar I am listing out various filtering options with the number or results associated with each filtering option (eBay style). In order to retrieve these filter options I perform a relationship search based on the search results. Since the search results only contain SkinnyItems it has to call GetItem() on every single result to get the actual item in order to get the value that I'm filtering by. In other words it will call Database.GetItem(id) 1000 times! Obviously that is not terribly efficient.
Am I missing something here? Is there any way to configure Sitecore search to retrieve custom values from the search index? If I can search for the values in the index why can't I also retrieve them? If I can't, how else can I process the results without getting each individual item from the database?
Here is an idea of the functionality that I’m after: http://cameras.shop.ebay.com.au/Digital-Cameras-/31388/i.html
Klaus answered on SDN: use facetting with Apache Solr or similar.
http://sdn.sitecore.net/SDN5/Forum/ShowPost.aspx?PostID=35618
I've currently resolved this by defining dynamic fields for every field that I will need to filter by or return in the search result collection. That way I can achieve the facetted searching that is required without needing to grab field values from the database. I'm assuming that by adding the dynamic fields we are taking a performance hit when rebuilding the index. But I can live with that.
In the future we'll probably look at utilizing a product like Apache Solr.
