I have string 'Vick's' that I need to pass to the cloud search using the API. But when I passing it to the API it throws an error. When I am using 'Vick's' instead of Vick's as a search string it is not giving exact result. The search for on the other hand 'Vick%27s' is working fine.
When I am in the Amazon and doing some searches there, they turn out fine for "Vick's" and "Vick\'s". I am using Amazing Cloud Search wrapper, which written in C#.
My question is: How to querying string with apostrophe in cloud search?
You'll need to prepend your ' with a slash (\'). And if you're using Java, and you're doing replaceAll, you'll need to do something along the lines of .replaceAll("'", "\\'") (4 slashes - even though only 2 appear here!).
Hope it helps!

I am new into Google Data Studio and I am trying to cleanse some Google Analytic data.
For example I have a filed called page which shows the page name. For some pages I have duplicates e.g: contact/product/car and contact/product/car/ (ending in this case with /)
I want to create a field that always replace the last charterer of the page name if it ends with '/' with a space
I have tried this function: REPLACE(ENDS_WITH(Page,"/"), '/','')
But is not working instead giving me true or false.
Someone can help me with this?
Please use regular expression for doing this job:
REGEXP_REPLACE(Page,"/$","")
Using C++, I've managed to follow the Xapian tutorial found here.
https://getting-started-with-xapian.readthedocs.io/en/latest/practical_example/index.html#
The indexer program works as I expect it to, but the search program - https://getting-started-with-xapian.readthedocs.io/en/latest/practical_example/searching/building.html - works only with a caveat.
When, for example, I run the equivalent of:
python2 code/python/search1.py db Dent watch
No matches are found, unless I instead write the following:
python2 code/python/search1.py db '"Dent" "watch"'
Which works as well as I expect. The problem is in not quite knowing why it works (though I know the '"' symbol is a search query modifier of some kind), and in how I should aim to prepare queries for processing.
For example, does the Xapian::QueryParser class constructor have an option to add the '"' symbols for me? Or should I preprocess input before I try to retrieve matches?
For the record, using the following queryParser.parse_query(input, queryParser.FLAG_PHRASE) appear to fix the issue I had.
I tried for few hours to find the right syntax for making a regex query that returns reviews from 2-3 different projects but I failed and decided to crowdsource the task ;)
The search is documented at https://review.openstack.org/Documentation/user-search.html and mentions possible use of REGEX,... but it just didn't work.
Task: return all CRs from openstack-infra/gerritlib and openstack-infra/git-review projects from https://review.openstack.org
Doing it for one project works well project:openstack-infra/gerritlib
Ideally I would like to look for somethign like ^openstack-infra\/(gerritlib|git-review), or at least this is the standard regex syntax.
Still, I found impossible to use parentheses so far, every time I used them it stopped it from returning any results.
1) You don't need to escape the "/" character.
2) You need to use double quotes to make the parentheses work.
So the following search should work for you:
project:"^openstack-infra/(gerritlib|git-review)"
I need to create a regex to help determine the number the number of times an API is called. We have multiple APIs and this API is of the following format:
/foo/bar/{barId}/id/{id}
The above endpoint also supports query parameters so the following requests would be valid:
/foo/bar/{barId}/id/{id}?start=0&limit=10
The following requests are also valid:
/foo/bar/{barId}/id/{id}/
/foo/bar/{barId}/id/{id}
We also have the following endpoints:
/foo/bar/{barId}/id/type/
/foo/bar/{barId}/id/name/
/foo/bar/{barId}/id/{id}/price
My current regex to extract calls made only to /foo/bar/{barId}/id/{id} looks something like this:
\/foo\/bar\/(.+)\/id\/(?!type|name)(.+)
But the above regex also includes calls made to /foo/bar/{barId}/id/{id}/price endpoint.
I can check if the string after {id}/ isn't price and exclude calls made to price but it isn't a long term solution since if we add another endpoint we may need to update the regex.
Is there a way to filter calls made only to:
/foo/bar/{barId}/id/{id}
/foo/bar/{barId}/id/{id}/
/foo/bar/{barId}/id/{id}?start=0&limit=10
Such that /foo/bar/{barId}/id/{id}/price isn't also pulled in?
\/foo\/bar\/(.+)\/id\/(?!type|name)(.+)
There is something in your RegEx which is the cause to your problem. "(.+)" RegEx code matches every character after it. So replace it with "[^/]" and add the following code "/?(?!.+)". This is working for me.
/foo/bar/([^/]+)/id/(?!type|name)([^/]+)/?(?!.+)
I'm using RGoogleAnalytics, I'm just at the learning stage at the moment.
I'm following the code in the tutorial here https://code.google.com/p/r-google-analytics/
But when I try to run
ga.goals <- conf$GetGoals()
ga.goals
I get an error message telling me there is an unexpected escaped character '\.' at pos 7
I get a similar message for the next two lines of code (GetSegments)
This question deals with a similar problems in the Facebook Graphs API
How to replace "unexpected escaped character" in R
I've tried using a similar bit of code
confGoalsSub <- gsub('\\.', ' ', conf$GetGoals())
to remove the escaped characters, but I get another error :
cannot coerce type 'closure' to vector of type 'character'
Out of desperation I have tried confGoalsSub <- gsub('\\.', ' ', conf) which returns a character vector that is just garbage (it's just the code for conf with the decimal points stripped out).
Can anyone suggest a better expression than gsub that will return a useful object?
EDIT: As per the suggestion below I've now added the brackets at the end of the function call but I still get the same error message about unexpected escape characters. I get the same error when I try to call other, similar function such as $GetSegments().
I saw on one video at the weekend that this package was broken for a long time, although the speaker did not provide details as to why. Perhaps I should give up and try one of the other Google Analytics packages in R.
Seems odd, given that this one is supposed to be Google supported.
I think this error arises when the RJSON library isn't able to parse the Google Analytics Data Feed properly and convert it into a nested list. The updated version of [RGoogleAnalytics] (http://cran.r-project.org/web/packages/RGoogleAnalytics/index.html) fixes this problem. Currently, you won't be able to retrieve Goals and Segments from your Google Analytics account using the library but beyond that it supports the full range of dimensions and metrics.
