How do we write an OSGI Service that takes tag value and finds pages which are having tag value?

Hello @Dvaraka 

You could use a service to use https://developer.adobe.com/experience-manager/reference-materials/6-5/javadoc/index.html?com/day/cq... and pass desired tag id or path to get resources tagged with the tag.

Below is an example from https://github.com/adobe/aem-core-wcm-components/blob/main/bundles/core/src/main/java/com/adobe/cq/w... 

private void populateTagListItems() {
        listItems = new ArrayList<>();
        String[] tags = properties.get(PN_TAGS, new String[0]);
        boolean matchAny = properties.get(PN_TAGS_MATCH, TAGS_MATCH_ANY_VALUE).equals(TAGS_MATCH_ANY_VALUE);
        if (ArrayUtils.isNotEmpty(tags)) {
            Page rootPage = getRootPage(PN_TAGS_PARENT_PAGE);
            if (rootPage != null) {
                TagManager tagManager = resourceResolver.adaptTo(TagManager.class);
                RangeIterator<Resource> resourceRangeIterator = tagManager.find(rootPage.getPath(), tags, matchAny);
                if (resourceRangeIterator != null) {
                    while (resourceRangeIterator.hasNext()) {
                        Page containingPage = pageManager.getContainingPage(resourceRangeIterator.next());
                        if (containingPage != null) {
                            listItems.add(containingPage);
                        }
                    }
                }
            }
        }
    }
