textsearch | Find strings/words in text ; convenience and C speed | Regex library

When using Postgres you can index a string in a database field as a vector using ts_vector. (https://www.postgresql.org/docs/10/datatype-textsearch.html#DATATYPE-TSVECTOR)

Is there a similar concept for ElasticSearch?

Currently, I'm having a weird issue with regards to rendering my API. (I'm using Expo GO)

I'm using Axios, which calls the API inside of a UseEffect once I get location of the device. The problem I'm facing is that the screen only renders the fetched data once I save or cntrl+s on VS Code.

I've tried to log the array, get nothing once the function is called. I've also tried adding a button to call the function instead, only then it renders, which makes sense as it triggers a re-render.

WHEN I ENTER THE COMPONENT: enter image description here

WHEN I SAVE THE FILE, IT THEN FETCHES DATA: enter image description here

Would be much appreciated if anyone can help, maybe I'm missing some basic knowledge of how this works. Thanks guys!

I need help with this bug on my MERN website as I can't figure out how to fix this step on my own.

Every time the users make changes to the backend, I want to re-render it and display it on the UI - without having to refresh the page.

But in my case, everything is working as I expected but there is still 1 last problem:

The process:

• On begin, the website will display a foodList table with all data from the backend.
• When the users use the Filter & Search Bar to find what they want to see. Behind the scenes, it will make a search from filtering out the items in foodList array and then put it to the searchedFood array. All the search results will be returned in the searchedFood table.
• On searching, the page will hide the foodList table and display the searchedFood table.
• When users click on the clearSearch button, it will bring the foodList data table back and hide the searchedFood.

What's working:

• When I make changes on the foodList table, it will re-render and display the changes instantly. It will also re-render the searchedFood table when I try to search for that changed item after - all without having to refresh the page.

• When I search for an item and then make changes on a searched item (Which is on the searchedFood table) - it will re-render and display the changes instantly.

What's not working:

• But then I click the clearSearch button to return to the full foodList table. The changes I just made in searchedFood won't re-render automatically on foodList - I need to refresh the page in order to see the changes I've made.

As I understand, there's something missing in the return to the foodList table step that isn't triggering the re-render. But what can we do and how to implement it in my code?

I want to setup a Postgres "stored generated columns" with indexing to have full text search on two fields of a model. I created the generated column getting help from this tutorial, but when setting gin index on the column, I get this:

This might be a simple duplicate question but I couldn't find any solution that resolve my case below. Please help me out! :)

I'm looking for a string method to check if the value matches a specific string and return that result.

• I'm using create-react-app and I have a dropdown for users to filter dishes with a specific price range This dropdown has 3 values which are strings: "$", "$$" and "$$$" I'm currently using the .includes method and not getting the result I want because it includes all the results that contain a character from the string. (If users choose "$", it will also return the results including "$$" and "$$$") -> I only want them to return the results with exactly the value of strings above. So what to use instead of .includes ? // Initial states: const [foodList, setFoodList] = useState([]) const [foodName, setFoodName] = useState('') const [isVegetarian, setIsVegetarian] = useState('') const [priceRange, setPriceRange] = useState('$') const [textSearch, setTextSearch] = useState('') const [priceDropdown, setPriceDropdown] = useState('') const [vegDropdown, setVegDropdown] = useState('') // Search.js: const newSearch = props.foodList.filter((value) => { return ( value.foodName.toLowerCase().includes(textSearch.toLowerCase()) && // What to use instead of .includes here? value.priceRange.toLowerCase().includes(priceDropdown.toLocaleLowerCase()) && value.isVegetarian.includes(vegDropdown.toLowerCase()) ) } )

I am trying to center a dcc.input text field to the middle of the screen, however the solutions found here: Plotly Dash center dcc.Input text field nor the https://dash.plotly.com/dash-core-components/input page has proven to fix the problem. My code is:

We are using GridGain Community edition : 8.8.10 and have created Ignite Cluster in Kubernetes using the Apache Ignite operator. We have enabled native persistence also.

https://ignite.apache.org/docs/latest/installation/kubernetes/gke-deployment

In the development environment we shutdown our cluster during the night and bring it up during morning hours. When the cluster comes up it contains the data which was stored earlier. If we search the cache using key then it returns the result, but if we use the Query API for partial search then it is not returning results. We checked the cache size and it matches the datasource record size. Also after we search the Cache using the cache key, then that entry is available in the Query search results.

If we shut-down one of the nodes of the Ignite Cluster or client nodes. The TextSearch still works. TextSearch doesn't works only when all the nodes of the cluster are scaled-down and then scaled up using the existing disk.

Is there any configuration required to enable Query search after cold restart of the Ignite cluster ?

I have a problem with my and I really don't know where the error is.

This is my SearchBar

I have a lookup table of data in Sheet1 where all the names in columns A and B will be unique, so no names in either A will exist in B and vice-versa. However, some names could include special characters like a hyphen or dash such as O'neil or Jamie-lee

I have another table of data in Sheet2, in which I need to use the text string in column D to find a matching name in Sheet1 (in either column A or B) and then assign the Score value of the row on sheet1 if a match is found into Sheet2 column E.

I have entered the matched score values in column E to demonstrate the outcome I require. I don't mind using VBA or an Excel formula that works in XL2010

Is it possible to use a text string to find a word match, as I've only seen it the other way around, or am I looking at this the wrong way? I just don't seem to be getting anywhere.

I have change the code so often now trying to get it to work, I think I'm a bit lost, but this is the current state of my code that isn't working:
