Hi Shruthi,

Greetings to you!

Please try the below code, I have tested in my org and it is working fine. Kindly modify the code as per your requirement.

Apex:
public class SearchKeyupC {
    
    @AuraEnabled
    public static List<Account> search(String key){
        String keyword = key + '%' ;
        List<Account> sr = [SELECT Name, Phone, Rating FROM Account WHERE Name LIKE:keyword];
        return sr;
    }
}

Component:
<aura:component controller="SearchKeyupC"
                implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" access="global" >
    
    <aura:attribute name="PageHeading" type="String" default="Search Accounts"/>
    <aura:attribute name="SearchKeyword" type="String" />
    <aura:attribute name="mydata" type="Account"/>
    <aura:attribute name="mycolumns" type="List"/>
    
    <aura:handler name="init" value="{!this}" action="{!c.init}" />
    
    <div class="slds-m-top--xx-large">
        <div class="slds-page-header">
            <div class="slds-align--absolute-center">
                <div class="slds-text-heading--large">       
                    {!v.PageHeading}
                </div>
            </div>
        </div>
    </div>
    <br/> <br/>
    
    <div class = "slds-size--3-of-8">
        <ui:inputText aura:id="searchInput" 
                      label="Search " 
                      keyup="{!c.doSearch}" 
                      updateOn="keyup" />
        <br/><br/><br/>
    </div>
    
    <lightning:datatable data="{! v.mydata }" 
                         columns="{! v.mycolumns }" 
                         keyField="Id" />
</aura:component>

Controller:
({
    init : function(component, event, helper) {
        component.set('v.mycolumns', [
            {label: 'Account Name', fieldName: 'Name', type: 'text'},
            {label: 'Phone', fieldName: 'Phone', type: 'text'},
            {label: 'Rating', fieldName: 'Rating', type: 'text'}
        ]);       
    },
    
    doSearch : function(component, event, helper) {
        var searchInput = component.find("searchInput");
        var searchValue = searchInput.get("v.value");
        if (searchValue == '' || searchValue == null) {
            component.set("v.mydata", " ");
        }
        else{
            var action = component.get("c.search");
            action.setParams({key : searchValue});
            action.setCallback(this, function(response) {
                var state = response.getState();
                if (state === "SUCCESS") {
                    console.log(response.getReturnValue());
                    component.set("v.mydata", response.getReturnValue());
                }
                else if (state === "ERROR") {
                    var errors = response.getError();
                    if (errors) {
                        if (errors[0] && errors[0].message) {
                            console.log("Error message: " + 
                                        errors[0].message);
                        }
                    } 
                    else {
                        console.log("Unknown Error");
                    }
                }
            });
            $A.enqueueAction(action);
        }
    }
})

CSS:
.THIS {

}

.THIS.slds-size--3-of-8 {
    
    margin-left: 620px;
}

Application:
<aura:application extends="force:slds">
    <c:SearchKeyup/>
</aura:application>

I hope it helps you.
