How do a keyword search in kibana4 dashboard - elasticsearch

I have a kibana Dashboard with data table visualization, In that visualization widget, I need to scroll down or change pagination.i have 1800 city name in that single visualization widget, if I want to go to city name starts with K...., it's very hard for me to search for each page
NOTE: I have an not analyzed data.

In the search bar at the top, I believe you can use Lucene expressions.
Try:
city:K*

How to update the data source of a dashboard in Kibana

I have a dashboard with some visualizations on it. Recently, we have a new data source that is a saved search, and we need to change the index pattern of the dashboard to the saved search.
This is my first time working with kibana. I'm considering changing the index pattern of each panel on the dashboards. But when I edit the reference of the visualization to the id of the saved search, the visualization could not open. Is there anyway to change the data source of a visualization?
I don't believe that is possible. Read this post.

Get percentage based on count in elasticsearch

I have an index of objects that contains:
username (nullable)
status (can be "none", "talking" or "customer")
I need to get the conversion rate of users (per user) based on how many objects that has status "talking" against objects that has status "customer".
And then represent this in a some chart.
Is this possible?
Below are the steps to achieve this:
Go to kibana Management -> Index Patterns -> Create index pattern and then type the name of your index for e.g myindex
Go to Visualize tab. Click on + and select Pie. Check this LINK
Select the index name for e.g. myindex
Click on Split Slices. And then select Terms. Select status in the field section.
Click on the bluish green play button which would display Apply changes when you hover your mouse
You would now be able to see the pie chart with all the values.
Now for only customer and talking, click on Add a filter
Select status in the field.
Select is one of operator and then select both customer and talking values.
You should now be able to see pie chart with only these two values. If you hover the mouse on the pie chart, you would be able to see the percentages respectively.
Below is how it appears on my kibana machine where I had three documents whose status as talking and two documents with status as customer
Note In my mapping I've used the status.keyword as field of type keyword in order to run Terms Aggregation
Let me know if this helps!

Can not add custom field to Y-Axis Average aggregation for visualization

When I try to add Bar Chart visualization, I cannot select any custom field for my messages for Average aggregation (like: "my_custom_field"). Messages are logged and contain this field. How to do this?
I have a strong suspicion that your "messages" field is a string. Average aggregation works on numbers.
I checked this in my own setting and I couldn't run Average on "messages" with default settings, but I could run it on Unique Count.
I don't understand why, but when I create visualization via Visualizations tab/Add new/Vertical bar chart, fields are not present.
But, I can make visualization by:
[OPTIONAL, probably didn't help] Go to Management/Index Patterns and click Refresh image button in right top corner. This will create mapping types for fields that are new since index creation (this was in my case). Such field can be recognized when before its name there is "?", means no type (e.g. # means field has type, like on the image below).
Go to Discover tab and select your field on the left, than click Visualize -> that will allow to select Average aggregate with your field.
This is very inconvenient, but works.

Static List in Kibana 4

I would like to create a static list on Kibana Dashboard.
For example, a pane displaying clickable region names. So when I click on a region, rest of the visualizations change dynamically.
I am looking for something like 'Metric' visualization but for text data and clickable.
Is there a way to do this?
We do something similar, not fully static, but you can create a Data Table visualization (in Kibana4).
On that table, filter by the logs that interest you (with the metric types for example) and that will create a row for each metric type. Add that table visualization to the dashboard where you need the 'clickable filter'.
Then, clicking a row in that table will filter the entire dashboard based on that specific metric-type.

D3: Is there a name for this type of chart and code example?

I've seen this kind of bar chart in a couple of places. This is from LinkedIn. The page is rather complicated.
When you click on a bar, it recalculates and reorders the bars in the other columns. Here, San Fran is clicked.
Is there an example of something like this in d3?
Is there any specific name for it?
In general, this is known as a faceted search which generates the data that powers the visualization. The two parts to this, the data and the visualization, are described below along with some links to integrated D3.js / ElasticSearch examples.
Data: Faceted Search / Aggregation
The data produces a histogram by counting facets across a set of items. Traditionally, this was done (efficiently) as a faceted search in a fulltext search engine like Lucene and ElasticSearch (built on Lucene). ElasticSearch now calls this capability aggregations. The data is calculated fast enough that it is done in real time for searches.
In the LinkedIn example, you would create a search index of people with fields like those listed. Then using a faceted search, you can easily get counts of documents (people) with each facet value. In your query, you can also say you want say the top x (10) most popular values.
For more info see the following links. The first is more detailed while the second and third are higher level.
Lucene Faceted Search User's Guide
ElasticSearch Documentation on Facets
ElasticSearch Documentation on Aggregations (new approach)
Visualization: Horizontal Bar Chart
Once you have the data, the visualization is a combination of sorting by highest count and a simple horizontal bar chart which can be generated using a variety of means. The following links use D3.js directly or NVD3.js which is a helper library for making common charts. To get the desired effect, you may have to link clicks to new searches with updated parameters.
D3 JS Simple Horizontal Bar chart
NVD3.js Horizontal Multi-Bar chart (use a single series)
Integrated Examples
Here are some links for pre-built integrations using D3.js and faceted search / aggregations.

Elastic List seems to be the closest answer.
